A CONTROLLED-ACCESS HIGHWAY is a type of highway which has been
designed for high-speed vehicular traffic, with all traffic flow and
ingress/egress regulated. Common English terms are FREEWAY (in
Australia and parts of the
United States and Canada), MOTORWAY (in the
United Kingdom, Ireland and New Zealand) and EXPRESSWAY (some parts of
Canada, parts of the United States, and many Asian countries). Other
similar terms include Interstate and parkway . Some of these may be
limited-access highways , although this term can also refer to a class
of highway with somewhat less isolation from other traffic.
In countries following the Vienna convention , the motorway
qualification implies they are forbidden for walking or parking, and
reserved for the use of motorised vehicles only.
A controlled-access highway provides an unhindered flow of traffic,
with no traffic signals , intersections or property access . They are
free of any at-grade crossings with other roads, railways, or
pedestrian paths, which are instead carried by overpasses and
underpasses . Entrances and exits to the highway are provided at
interchanges by slip roads (ramps), which allow for speed changes
between the highway and arterials and collector roads . On the
controlled-access highway, opposing directions of travel are generally
separated by a median strip or central reservation containing a
traffic barrier or grass. Elimination of conflicts with other
directions of traffic dramatically improves safety and capacity.
Controlled-access highways evolved during the first half of the 20th
Italy opened its first autostrada in 1924, A8 , connecting
Germany began to build its first controlled-access
autobahn without speed limits (30-kilometre (19 mi) on what is now
A555 , then referred to as a dual highway) in 1932 between
Bonn . It then rapidly constructed a nationwide system of such roads.
The first North American freeways (known as parkways) opened in the
New York City
New York City area in the 1920s. Britain, heavily influenced by the
railways, did not build its first motorway, the
Preston By-pass (M6 ),
Most technologically advanced nations feature an extensive network of
freeways or motorways to provide high-capacity urban travel, or
high-speed rural travel, or both. Many have a national-level or even
international-level (e.g. European E route ) system of route numbering

There are several international standards which give some definitions
of words such as motorways, but there is no formal definition of the
English language words "motorway", "freeway" and "expressway", or of
the equivalent words in other languages such as "autoroute",
"Autobahn", "autostrada", "autocesta", that are accepted
worldwide—in most cases these words are defined by local statute or
design standards or regional international treaties. Descriptions that
are widely used include:
Vienna Convention on Road Signs and Signals
Vienna Convention on Road Signs and Signals
"Motorway" means a road specially designed and built for motor
traffic, which does not serve properties bordering on it, and which:
* Is provided, except at special points or temporarily, with
separate carriageways for the two directions of traffic, separated
from each other either by a dividing strip not intended for traffic
or, exceptionally, by other means;
* Does not cross at level with any road, railway or tramway track,
or footpath; and,
* Is specially sign-posted as a motorway;
One green or blue symbol (like ) appears at motorway entry in
countries which follow Vienna Convention. Exit is marked with another
The definitions of "motorway" from the OECD and PIARC are almost
British Standards Motorway: Limited-access dual
carriageway road, not crossed on the same level by other traffic lanes
, for the exclusive use of certain classes of motor vehicle. ITE
(including CITE ) Freeway: A divided major roadway with full control
of access and with no crossings at grade. This definition applies to
toll as well as toll-free roads. Freeway A: This designates roadways
with greater visual complexity and high traffic volumes. Usually this
type of freeway will be found in metropolitan areas in or near the
central core and will operate through much of the early evening hours
of darkness at or near design capacity. Freeway B: This designates all
other divided roadways with full control of access where lighting is
In the European Union, for statistic and safety purposes, some
distinction might be made between motorway and expressway, for
instance a principal arterial might be considered as:
Roads serving long distance and mainly interurban movements. Includes
motorways (urban or rural) and expressways (road which does not serve
properties bordering on it and which is provided with separate
carriageways for the two directions of traffic). Principal arterials
may cross through urban areas, serving suburban movements. The traffic
is characterized by high speeds and full or partial access control
(interchanges or junctions controlled by traffic lights). Other roads
leading to a principal arterial are connected to it through side
In this view, CARE's definition stands that a motorway is understood
public road with dual carriageways and at least two lanes each way.
All entrances and exits are signposted and all interchanges are grade
separated. Central barrier or median present throughout the road. No
crossing is permitted, while stopping is permitted only in an
emergency. Restricted access to motor vehicles, prohibited to
pedestrians, animals, pedal cycles, mopeds, agricultural vehicles. The
minimum speed is not lower than 50 km/h and the maximum speed is not
higher than 130 km/h (Except
Germany where no speed limit is
Motorways are designed to carry heavy traffic at high speed with the
lowest possible number of accidents. They are also designed to collect
long-distance traffic from other roads, so that conflicts between
long-distance traffic and local traffic are avoided. According to the
common European definition, a motorway is defined as "a road,
specially designed and built for motor traffic, which does not serve
properties bordering on it, and which: (a) is provided, except at
special points or temporarily, with separate carriageways for the two
directions of traffic, separated from each other, either by a dividing
strip not intended for traffic, or exceptionally by other means; (b)
does not cross at level with any road, railway or tramway track, or
footpath; (c) is specially sign-posted as a motorway and is reserved
for specific categories of road motor vehicles. Urban motorways are
also included in this definition. However, the respective national
definitions and the type of roads covered may present slight
differences in different EU countries.
Historical map of the original A8-A9 motorway, Italy. The first
motorway ever built in the world was opened on 21 September 1924.
The first version of modern controlled-access highways evolved during
the first half of the 20th century. The
Long Island Motor
Long Island , New York , opened in 1908 as a private venture, was the
world's first limited-access roadway. It included many modern
features, including banked turns, guard rails and reinforced concrete
Modern controlled-access highways originated in the early 1920s in
response to the rapidly increasing use of the automobile , the demand
for faster movement between cities and as a consequence of
improvements in paving processes, techniques and materials. These
original high-speed roads were referred to as "dual highways" and,
while divided, bore little resemblance to the highways of today.
Opened in 1921, the
Berlin is the oldest controlled-access
highway in Europe, although it was initially opened as a race track.
The first dual highway opened in
Italy in 1924, between
Varese , and now forms parts of the A8 and A9 motorways. This highway,
while divided, contained only one lane in each direction and no
interchanges. Shortly thereafter, in New York in 1924, the Bronx River
Parkway was opened to traffic. The Bronx River
Parkway was the first
North America to utilize a median strip to separate the
opposing lanes, to be constructed through a park and where
intersecting streets crossed over bridges. The Southern State
Parkway opened in 1927, while the
Long Island Motor
Parkway was closed
in 1937 and replaced by the Northern State
Parkway (opened 1931) and
the contiguous Grand Central
Parkway (opened 1936). In Germany,
construction of the Bonn-
Cologne autobahn began in 1929 and was opened
in 1932 by the mayor of Cologne.
Canada , the first precursor with semi-controlled access was The
Road between Hamilton and Toronto, which featured a median
divider between opposing traffic flow, as well as the nations first
cloverleaf interchange . This highway developed into the Queen
Elizabeth Way , which featured a cloverleaf and trumpet interchange
when it opened in 1937, and until the
Second World War
Second World War , boasted the
longest illuminated stretch of roadway built. A decade later, the
first section of
Highway 401 was opened, based on earlier designs. It
has since gone on to become the busiest highway in the world.
The word freeway was first used in February 1930 by Edward M. Bassett
. Bassett argued that roads should be classified into three basic
types: highways, parkways , and freeways. In Bassett's zoning and
property law -based system, abutting property owners have the rights
of light, air and access to highways, but not parkways and freeways;
the latter two are distinguished in that the purpose of a parkway is
recreation, while the purpose of a freeway is movement. Thus, as
originally conceived, a freeway is simply a strip of public land
devoted to movement to which abutting property owners do not have
rights of light, air or access.

Southern Ontario , Canada. An example of a
collector-express freeway design, the route features four carriageways

France showing hard
shoulder and emergency telephone. The broken demarcation line for the
hard shoulder is specific to France, and serves as a safety reference
mark for drivers: the advisory distance from the vehicle ahead is two
Freeways, by definition, have no at-grade intersections with other
roads, railroads or multi-use trails , and no traffic signal needed,
hence "free of signal", but some Movable bridges , such as the
Interstate Bridge on
Interstate 5 between
Oregon and Washington , do
require drivers to stop for ship traffic.
The crossing of freeways by other routes is typically achieved with
grade separation either in the form of underpasses or overpasses . In
addition to sidewalks (pavements) attached to roads that cross a
freeway, specialized pedestrian footbridges or tunnels may also be
provided. These structures enable pedestrians and cyclists to cross
the freeway at that point without a detour to the nearest road
Access to freeways is typically provided only at grade-separated
interchanges , though lower-standard right-in/right-out access can be
used for direct connections to side roads. In many cases,
sophisticated interchanges allow for smooth, uninterrupted transitions
between intersecting freeways and busy arterial roads . However,
sometimes it is necessary to exit onto a surface road to transfer from
one freeway to another. One example in the
United States (notorious
for the resulting congestion) is the connection from
Interstate 70 to
Pennsylvania Turnpike (
Interstate 70 and Interstate 76 ) through
the town of
Breezewood, Pennsylvania .
Speed limits are generally higher on freeways and are occasionally
nonexistent (as on much of Germany\'s
Autobahn network). Because
higher speeds reduce decision time, freeways are usually equipped with
a larger number of guide signs than other roads, and the signs
themselves are physically larger. Guide signs are often mounted on
overpasses or overhead gantries so that drivers can see where each
lane goes. Exit numbers are commonly derived from the exit's distance
in miles or kilometers from the start of the freeway. In some areas,
there are public rest areas or service areas on freeways, as well as
emergency phones on the shoulder at regular intervals.
In the United States, mileposts start at the southern or westernmost
point on the freeway (either its terminus or the state line).
Nevada use postmile systems in which the markers
indicate mileage through the state's individual counties. However,
Ohio also use the standard milepost system concurrently
with their respective postmile systems.
California numbers its exits
off of its freeways according to a milepost system but does not use
milepost markers. Diagram showing lanes and road layout (Irish
Two-lane freeways , often undivided, are sometimes built when traffic
volumes are low or right-of-way is limited; they may be designed for
easy conversion to one side of a four-lane freeway. (Most of the Bert
T. Combs Mountain
Parkway in Eastern Kentucky is two lanes, but work
has begun to make all of it four-lane.) These are often called Super
two roads. Several such roads are infamous for a high rate of lethal
crashes; an outcome because they were designed for short sight
distances (sufficient for freeways without oncoming traffic, but
insufficient for the years in service as two-lane road with oncoming
traffic). An example of such a "
Highway to Hell" was
European route E4
Gävle to Axmartavlan , Sweden. The high rate of crashes with
severe personal injuries on that (and similar) roads did not cease
until a median crash barrier was installed, transforming the fatal
crashes into non-fatal crashes. Otherwise, freeways typically have at
least two lanes in each direction; some busy ones can have as many as
16 or more lanes in total.
In San Diego,
Interstate 5 has a similar system of
express and local lanes for a maximum width of 21 lanes on a
3.2-kilometre (2 mi) segment between
Interstate 805 and California
State Route 56 . In
Mississauga , Ontario,
Highway 401 uses
collector-express lanes for a total of 18 lanes through its
Highway 403 /
Highway 410 and
Highway 427 .
These wide freeways may use separate collector and express lanes to
separate through traffic from local traffic, or special high-occupancy
vehicle lanes , either as a special restriction on the innermost lane
or a separate roadway, to encourage carpooling . These HOV lanes , or
roadways open to all traffic, can be reversible lanes , providing more
capacity in the direction of heavy traffic, and reversing direction
before traffic switches. Sometimes a collector/distributor road , a
shorter version of a local lane, shifts weaving between closely spaced
interchanges to a separate roadway or altogether eliminates it.
In some parts of the world, notably parts of the US , frontage roads
form an integral part of the freeway system. These parallel surface
roads provide a transition between high-speed "through" traffic and
local traffic. Frequent slip-ramps provide access between the freeway
and the frontage road, which in turn provides direct access to local
roads and businesses.
Except on some two-lane freeways (and very rarely on wider freeways),
a median separates the opposite directions of traffic. This strip may
be as simple as a grassy area, or may include a crash barrier such as
Jersey barrier " or an "
Ontario Tall Wall" to prevent head-on
collisions . On some freeways, the two carriageways are built on
different alignments; this may be done to make use of available
corridors in a mountainous area or to provide narrower corridors
through dense urban areas .
CONTROL OF ACCESS
Control of access relates to a legal status which limits the types of
vehicles that can use a highway, as well as a road design that limits
the points at which they can access it.
Freeways are usually limited to motor vehicles of a minimum power or
weight; signs may prohibit cyclists , pedestrians and equestrians and
impose a minimum speed. It is possible for non-motorized traffic to
use facilities within the same right-of-way, such as sidewalks
constructed along freeway-standard bridges and multi-use paths next to
freeways such as the
Suncoast Trail along the Suncoast
Florida . De Lucht Rest Area on the Dutch A2 - A typical rest
area in the
Netherlands with services (fuel, refreshments and
toilets). The only access is via the highway that it serves.
In some US jurisdictions, especially where freeways replace existing
roads, non-motorized access on freeways is permitted. Different states
United States have different laws. Cycling on freeways in
Arizona may be prohibited only where there is an alternative route
judged equal or better for cycling. Wyoming, the least populated
state, allows cycling on all freeways.
Oregon allows bicycles except
on specific urban freeways in Portland and Medford .
In countries such as the
United Kingdom new motorways require an Act
of Parliament to ensure restricted right of way. Since upgrading an
existing road (the "Queen's Highway") to a full motorway will result
in extinguishing the right of access of certain groups such as
pedestrians, cyclists and slow-moving traffic, many controlled access
roads are not full motorways. In some cases motorways are linked by
short stretches of road where alternative rights of way are not
practicable such as the
Dartford Crossing (the furthest downstream
public crossing of the
River Thames ) or where it was not economic to
build a motorway alongside the existing road such as the former
Cumberland Gap . The A1 is a good example of piece-wise upgrading to
motorway standard—as of January 2013, the 639-kilometre-long (397
mi) route had five stretches of motorway (designated as A1(M)).
Continental European non-motorway dual carriageways can have limits
as high as 110–130 km/h (68–81 mph).
Research shows 85 percent of motor vehicle-bicycle crashes follow
turning or crossing at intersections. Freeway travel eliminates
almost all those conflicts save at entrance and exit ramps—which, at
least on those freeways where cycling has not been banned, have
sufficient room and sight for cyclists and motorists. An analysis of
Arizona showed no safety problems with cycling on freeways.
Fewer than one motor vehicle-bicycle crash a year was recorded on
nearly 3,200 shoulder kilometres (2,000 mi) open to cyclists in
Major arterial roads will often have partial access control, meaning
that side roads will intersect the main road at grade, instead of
using interchanges, but driveways may not connect directly to the main
road, and drivers must use intersecting roads to access adjacent land.
At arterial junctions with relatively quiet side roads, traffic is
controlled mainly by two-way stop signs which do not impose
significant interruptions on traffic using the main highway.
Roundabouts are often used at busier intersections in Europe because
they help minimize interruptions in flow, while traffic signals that
create greater interference with traffic are still preferred in North
America. There may be occasional interchanges with other major
arterial roads. Examples include US 23 between SR 15 's eastern
terminus and Delaware,
Ohio , along with SR 15 between its eastern
terminus and I-75 , US 30 , SR 29 /US 33 , and US 35 in western and
central Ohio. This type of road is sometimes called an EXPRESSWAY.
The most frequent way freeways are laid out is usually by building
them from the ground up after things such as forestry or buildings are
cleared away. Sometimes they deplete farmland, but other methods have
been developed for economic, social and even environmental reasons.
Full freeways are sometimes made by converting at-grade expressways
or by replacing at-grade intersections with overpasses; however, any
at-grade intersection that ends a freeway remains. Often, when there
is a two-lane undivided freeway or expressway, it is converted by
constructing a twin corridor on the side by leaving a median between
the two travel directions. The opposing side for the old two-way
corridor becomes a passing lane.
Other techniques involve building a new carriageway on the side of a
divided highway that has a lot of private access on one side and
sometimes has long driveways on the other side since an easement for
widening comes into place, especially in rural areas.
When a "third" carriageway is added, sometimes it can shift a
directional carriageway by 50–200 feet (15–61 m) (or maybe more
depending on land availability) as a way to retain private access on
one side that favors over the other. Other methods involve
constructing a service drive that shortens the long driveways
(typically by less than 100 metres (330 ft)).
INTERSECTIONS AND ACCESS POINTS
An intersection is a highway layout that permits traffic from one
controlled-access highway to access another and vice versa whereas an
access point is a highway layout where traffic from a distributor or
local road can join a controlled-access highway. Some countries, such
as the United Kingdom, do not distinguish between the two, but other,
such as Germany; make a distinction using the word Kreuz (cross) for
the former and Ausfahrt (exit) for the other. In all cases one road
crosses the other via a bridge.
The inter-connecting roads, or slip-roads, which link the two roads,
can follow any one of a number of patterns. The actual pattern is
determined by a number of factors including local topology, traffic
density, land cost, building costs, type of road, etc. In some
jurisdictions feeder/distributor lanes are common, especially for
cloverleaf interchanges ; in others, such as the United Kingdom, where
the roundabout interchange is common, feeder/distributor lanes are
A few of the more common types of junction are shown below:
VARIOUS INTERCHANGE LAYOUTS
Four-level stack: Used as a major junction, usually for freeway
Roundabout interchange: Very common in the
United Kingdom as
either a junction or exit.
Cloverleaf: Used mainly as a junction.
Parclo (partial cloverleaf) interchange: often used to link a
minor road with a junction.
Trumpet interchange: a motorway "T" junction
Motorways are the safest roads by design. While accounting for more
than one quarter of all kilometres driven, they contributed only 8% of
the total number of European road deaths in 2006. Germany's Federal
Highway Research Institute provided International
Road Traffic and
Accident Database (IRTAD) statistics for the year 2010, comparing
overall fatality rates with motorway rates (regardless of traffic
KILLED PER 1 BILLION VEH·KM
There are many differences between countries in their geography,
economy, traffic growth, highway system size, degree of urbanization
and motorization, etc.; all of which need to be taken into
consideration when comparisons are made.
According to Vinci Autoroutes one third of accidents in French
motorways are due to sleepy driving.
The German autobahn network illustrates the safety trade-offs of
controlled access highways. The injury crash rate is very low on
autobahns while 22 people died per 1000 injury crashes—although
autobahns have a lower rate than the 29 deaths per 1,000 injury
accidents on conventional rural roads, the rate is higher than the
risk on urban roads. Speeds are higher on rural roads and autobahns
than urban roads, increasing the severity potential of a crash.
According to ESTC, German motorways without a speed limit, but with a
130 km/h (81 mph) speed recommendation, are three times more deadly
than motorways with a speed limit.
Germany also introduced some 130 km/h (81 mph) speed limits on
various motorway sections which were not limited. This generated a
reduction in deaths in a range from 20% to 50% on those sections.

University of Barcelona study suggests that if tolls are
implemented on a controlled-access highway, drivers may seek
alternative routes to avoid paying the tolls. This may result in a
decrease of safety on roads which are not designed for heavy traffic.
SAFETY OF URBAN MOTORWAY
In United Kingdom, there are few study regarding impact of road
traffic accidents from existing and new urban motorway. In
particular, new urban motorway does not grant a reduction of traffic
In Italy, a study performed on urban motorway A56 Tangenziale di
Napoli showed than reduction of speed allows to decrease crash
In Marseille, France, from June 2009 to May 2010, CEREMA, the French
centre for studies on risk, mobility and environment, performed a
study on Marius a network of urban motorways. This study established a
link between accidents and traffic variables, :
* for single vehicle accidents, the 6-minute average speed on the
fast lane; and the time headway (on every lane),
* for multiple vehicle accidents, the occupancy, and the time
headway (for the middle lane).
The 150 km-long Marius network counts 292 injury accidents or
fatalities for 1.5 billions of vehicle-kilometres, that is 189 injury
accidents or fatalities for 1 billion of vehicle-kilometres.
Some european countries have improved safety of urban motorways, with
a set of to dynamically manage traffic flow in response to changing
volumes, speeds, and incidentstechnics, including:
* variable speed limits, line control, and speed harmonization
* Shoulder running with emergency refuge areas
* Queue warning and variable messaging
* 24/7 monitoring of traffic with cameras and/or in-pavement sensors
(both to detect incidents and identify when to reduce speed limits)
* Incident management
* Automated enforcement
* Specialized algorithms for temporary shoulder running, variable
speed limits, and/or incident detection and management
* Ramp metering (coordinated or independent function)
In 1994, it was assummed that lighting urban motorway would benefit
from more safety than unlighted ones .
In California, in 2001, a study has established, for urban freeways,
some Relationships Among Urban Freeway Accidents, Traffic Flow,
Weather and Lighting Conditions

wet freeways in darkness

Controlled-access highways have been constructed both between major
cities as well as within them, leading to the sprawling suburban
development found near most modern cities. Highways have been heavily
criticized by environmentalists, urbanists, and preservationists for
the noise, pollution, and economic shifts they bring. Additionally,
they have been criticized by the driving public for the inefficiency
with which they handle peak hour traffic.
Often, rural highways open up vast areas to economic development and
municipal services, generally raising property values. In contrast to
this, above-grade highways in urban areas are often a source of
lowered property values, contributing to urban decay . Even with
overpasses and underpasses, neighbourhoods are divided—especially
impoverished ones where residents are less likely to own a car, or to
have the political and economic influence to resist construction
efforts. Beginning in the early 1970s, the US Congress identified
freeways and other urban highways as responsible for most of the noise
exposure of the US population. Subsequently, computer models were
developed to analyze freeway noise and aid in their design to help
minimize noise exposure.
Some cities have implemented freeway removal policies in which
freeways have even been demolished and reclaimed as boulevards or
parks, notably in
Cheonggyecheon ), Portland (Harbor Drive ),
New York City
New York City (West Side
Central Artery ), San
Embarcadero Freeway ) and
Park East Freeway ).
An alternative to surface or above ground freeway construction has
been the construction of underground urban freeways using tunnelling
technologies. This has been extremely successful in the Australian
Sydney (which has five such freeways),
Melbourne (which has
two such freeways) and
Brisbane (which has three such freeways). This
has had the benefit of removing traffic from surface roads and in the
case of Melbourne's Eastlink Motorway, has helped preserve an
ecologically sensitive area from destruction.
Other Australian cities face similar problems (lack of available
land, cost of home acquisition, aesthetic problems and community
opposition). Brisbane, which also has to contend with physical
boundaries (the river) and heavy population increases, has embraced
underground tunnel freeways. There are currently two open to traffic
Clem Jones Tunnel (Clem7) and Airport Link ), one under construction
Legacy Way ) and one (East-West Link ) is currently in planning. All
of the tunnels are designed to act as an inner-city ring road or
bypass system and include provisions for public transport, whether
underground or in reclaimed space on the surface. In Canada, the
Highway 401 into
Detroit , known as the Herb Gray Parkway
, has been designed with numerous tunnels and underpasses which
provide land for parks and recreational uses.
Freeway opponents have found that freeway expansion is often
self-defeating: expansion simply generates more traffic. That is, even
if traffic congestion is initially shifted from local streets to a new
or widened freeway, people will begin to run errands and commute to
more remote locations. Over time, the freeway and its environs become
congested again as both the average number and distance of trips
increases. This idea is known as induced demand .
Urban planning experts such as Drusilla Van Hengel, Joseph DiMento
and Sherry Ryan argue that although properly designed and maintained
freeways may be convenient and safe, at least in comparison to
uncontrolled roads, they may not expand recreation, employment and
education opportunities equally for different ethnic groups, or for
people located in certain neighborhoods of a given city. Still, they
may open new markets to some small businesses .
Construction of urban freeways for the US Interstate
which began in the late 1950s, led to the demolition of thousands of
city blocks, and the dislocation of many more thousands of people. The
citizens of many inner city areas responded with the freeway and
expressway revolts . Through the study of Washington\'s response, it
can be shown that the most effective changes came not from executive
or legislative action, but instead from policy implementation. One of
the foremost rationales for the creation of the United States
Department of Transportation (USDOT) was that an agency was needed to
mediate between the conflicting interests of interstates and cities.
Initially, these policies came as regulation of the state highway
departments. Over time, USDOT officials re-focused highway building
from a national level to the local scale. With this shift of
perspective came an encouragement for alternative transportation, and
locally based planning agencies.
At present, freeway expansion has largely stalled in the United
States , due to a multitude of factors that converged in the 1970s:
higher due process requirements prior to taking of private property ,
increasing land values, increasing costs for construction materials,
local opposition to new freeways in urban cores, the passage of the
National Environmental Policy Act (which imposed the requirement that
each new federally funded project must have an environmental impact
statement or report) and falling gas tax revenues as a result of the
nature of the flat-cent tax (it is not automatically adjusted for
inflation), the tax revolt movement, and growing popular support for
high-speed mass transit in lieu of new freeways.

England and Wales , the numbers of major motorways followed a

on the same principle of zones. Running clockwise from the M1 the
zones were defined for Zones 1 to 4 based on the proposed M2 , M3 and
M4 motorways . The M5 and M6 numbers were reserved for the other two
planned long distance motorways. The
Preston Bypass , the UK's first
motorway, should have been numbered A6(M) under the scheme decided
upon, but it was decided to keep the number M6 as had already been
applied. Certain portions or bypasses of A-roads may be designated as
motorways, the name of these portions being given the suffix "(M)". An
example is the A1(M) .
Scotland , where the
Scottish Office (superseded by the Scottish
Government in 1999) rather than the Ministry of Transport and Civil
Aviation had the decision, there is no zonal pattern, but rather the
A-road rule is strictly enforced. It was decided to reserve the
numbers 7, 8 and 9 for Scotland. The M8 follows the route of the A8 ,
and the A90 became part of the M90 when the A90 was re-routed along
the path of the A85 .
Northern Ireland a distinct numbering system is used, which is
separate from the rest of the
United Kingdom , though the
classification of roads along the lines of A, B and C is universal
throughout the UK and the
Isle of Man . According to a written answer
to a parliamentary question to the
Northern Ireland Minister for
Regional Development , there is no known reason as to how Northern
Ireland's road numbering system was devised. However motorways, as in
the rest of the UK, are numbered M, with the two major motorways
Belfast being numbered M1 and M2 . The M12 is a short spur
of the M1 with the M22 being a short continuation (originally intended
to be a spur) of the M2. There are two other motorways, the short M3 ,
the M5 and a motorway section of the A8 road , known as the A8(M) .

Signage on the M6 near
Kinnegad in Ireland . This is a standard
sign in many European countries to indicate the start of motorway
regulations. In this case the appropriate motorway number is shown and
in accordance with Irish practice a continuous yellow line indicates a
motorway rather than a high-quality dual carriageway (HQDC).
Republic of Ireland
Republic of Ireland , motorway and national road numbering is
quite different from the UK convention. Since the passage of the Roads
Act 1993, all motorways are part of, or form, national primary roads .
These routes are numbered in series, (usually, radiating
Dublin , starting with the N1/M1) using numbers
from 1 to 33 (and, separately from the series, 50). Motorways use the
number of the route of which they form part, with an M prefix rather
than N for national road (or in theory, rather than R for regional
road). In most cases, the motorway has been built as a bypass of a
road previously forming the national road (e.g. the M7 bypassing roads
previously forming the N7 )—the bypassed roads are reclassified as
regional roads , although updated signposting may not be provided for
some time, and adherence to signage colour conventions is lax
(regional roads have black-on-white directional signage, national
routes use white-on-green).
Under the previous legislation, the Local Government (Roads and
Motorways) Act 1974, motorways theoretically existed independently to
national roads, however the short sections of motorway opened during
this act, except for the M50, always took their number from the
national road that they were bypassing. The older road was not
downgraded at this point (indeed, regional roads were not legislated
for at this stage). Older signage at certain junctions on the M7 and
M11 can be seen reflecting this earlier scheme, where for example N11
and M11 can be seen coexisting.
The M50 , an entirely new national road, is an exception to the
normal inheritance process, as it does not replace a road previously
carrying an N number. The M50 was nevertheless legislated in 1994 as
the N50 route (it had only a short section of non-motorway section
from the Junction 11 Tallaght to Junction 12 Firhouse until its
extension as the Southern Cross Motorway). The M50's designation was
chosen as a recognisable number. As of 2010, the N34 is the next
unused national primary road designation. In theory, a motorway in
Ireland could form part of a regional road.
Sign on a Swiss
Autostrada (A2/E35 near
Lugano , Switzerland)
Hungary , similar to Ireland, motorway numbers can be derived from
the original national highway numbers (1–7), with an M prefix
attached, e.g. M7 is on the route of the old
Highway 7 from Budapest
Lake Balaton and
Croatia . New motorways not following the
original Budapest-centred radial highway system get numbers M8, M9,
etc., or M0 in the case of the ring road around Budapest.
Also in the
Netherlands , motorway numbers can be derived from the
original national highway numbers, but with an A (Autosnelweg ) prefix
attached, like A9 .
Germany federal motorways have the prefix A (
Autobahn ). If the
following number is an odd number the motorway generally follows a
north–south direction, even-numbered motorways generally follow an
east–west direction. Other controlled-access (dual carriageways) in
Germany can be federal highways (Bundesstraßen), state highways
(Landesstraßen), district highways (Kreisstraßen) and city highways
(Stadtstraßen), each with their own numbering system.
In New Zealand, as well as in the Scandinavian countries, in Finland
Russia , motorway numbers are also derived from the state
highway route that they form a part of, but unlike
Ireland, they are not distinguished from non motorway sections of the
same state highway route. In the cases where a new motorway acts as a
bypass of a state highway route, the original state highway is either
stripped of that status or renumbered. A low road number means a road
suitable for long distance driving. In
Switzerland as of April 2011,
there are 1,763.6 kilometres (1,095.9 mi) of a planned 1,893.5
kilometres (1,176.6 mi) of motorway completed. The country is
mountainous with a high proportion of tunnels, there are 220 totaling
200 kilometres (120 mi), which is over 12% of the total motorway
Australia , motorway numbering varies from state to state.
Currently most states are adopting numbering systems with the prefix M
Pakistan , motorways are denoted with the prefix M, while
expressways are denoted with prefix E.
Belgium , motorways but also some dual carriageways have numbers
preceded by an A. However, those that also have an E-number are
generally referenced with that one. City ring and bypasses have
numbers preceded by an R, these also can be either motorways or dual
While the design characteristics listed above are generally
applicable around the globe, every jurisdiction provides its own
specifications and design criteria for controlled-access highways.
Transport in South Africa
South Africa , the term freeway differs from most other parts of
the world. A freeway is a road where certain restrictions apply. The
following are forbidden from using a freeway:
* a vehicle drawn by an animal;
* a pedal cycle (such as a bicycle);
* a motorcycle having an engine with a cylinder capacity not
exceeding 50 cm3 or that is propelled by electrical power;
* a motor tricycle or motor quadrucycle;
Drivers may not use hand signals on a freeway (except in emergencies)
and the minimum speed on a freeway is 60 km/h (37 mph). Drivers in the
rightmost lane of multi-carriageway freeways must move to the left if
a faster vehicle approaches from behind to overtake.
Despite popular opinion that "freeway" means a road with at least two
carriageways, single carriageway freeways exist, as is evidenced by
the statement that "the roads include 1,400 km of dual carriageway
freeway, 440 km of single carriageway freeway and 5,300 km of single
carriage main road with unlimited access."

Although some 11,000 kilometres (6,800 mi) of Brazilian highway is
built to motorway-standard, there is no distinct designation for
controlled-access highways in the Brazilian federal and state highway
systems . The term autoestrada (Portuguese for "motorway") is not
commonly used in Brazil; the terms estrada ("road") and especially
rodovia ("highway") are instead preferred. Nevertheless, the most
technically advanced motorways in
Brazil are defined Class 0 motorways
by the National Department of Transport Infrastructure (DNIT). These
motorways are built to safely allow for vehicular speeds of up to 130
km/h (81 mph)). In mountainous terrain, the maximum allowable grade is
5% and maximum allowable radius is 665 metres (2,182 ft) (with 12%
São Paulo state, with 4,700 kilometres (2,900 mi) of motorway, has

1953 as an upgrade of the earlier single-carriageway highway. That
same year, construction of the second carriageway of Rodovia Anchieta

See also: Interstate
Highway System US Interstate Highway
In the United States, a freeway is defined by the federal
Manual on Uniform Traffic Control Devices as a divided
highway with full control of access. This means two things. First,
adjoining property owners do not have a legal right of access,
meaning that they cannot connect their lands to the highway by
constructing driveways, although frontage roads provide access to
properties adjacent to a freeway in many places. When an existing road
is converted into a freeway, all existing driveways must be removed
and access to adjacent private lands must be blocked with fences or
Second, traffic on a freeway is "free-flowing". All cross-traffic
(and left-turning traffic) is relegated to overpasses or underpasses,
so that there are no traffic conflicts on the main line of the highway
which must be regulated by traffic lights, stop signs, or other
traffic control devices. Achieving such free flow requires the
construction of many overpasses, underpasses, and ramp systems. The
advantage of grade-separated interchanges is that freeway drivers can
almost always maintain their speed at junctions since they do not need
to yield to vehicles crossing perpendicular to mainline traffic.
In contrast, an expressway is defined as a divided highway with
partial control of access. Expressways may have driveways and
at-grade intersections, though these are usually less numerous than on
ordinary arterial roads.
Interstate 5 (I-5) in
This distinction was apparently first developed in 1949 by the
Special Committee on Nomenclature of what is now the American
Association of State
Highway and Transportation Officials . In turn,
the definitions were incorporated into AASHTO's official standards
book, the Manual on Uniform Traffic Control Devices, which would
become the national standards book of USDOT under a 1966 federal
statute. The same distinction has also been codified into the
statutory law of eight states:
Minnesota , Mississippi
North Dakota ,
Ohio , and
However, each state codified the federal distinction slightly
California expressways do not necessarily have to be
divided, though they must have at least partial access control. For
both terms to apply, in
Wisconsin , a divided highway must be at least
four lanes wide; and in
Missouri , both terms apply only to divided
highways at least 16 kilometres (10 mi) long that are not part of the
Highway System. In
North Dakota and
expressways may have "full or partial" access control and "generally"
have grade separations at intersections; a freeway is then defined as
an expressway with full access control. Ohio's statute is similar, but
instead of the vague word generally, it imposes a requirement that 50%
of an expressway's intersections must be grade-separated for the term
to apply. Only
Minnesota enacted the exact MUTCD definitions, in May
The term expressway is also used for what the federal government
calls "freeways". Where the terms are distinguished, freeways can be
characterized as expressways upgraded to full access control, while
not all expressways are freeways.
Examples in the
United States of roads which are technically
expressways (under the federal definition), but contain the word
"freeway" in their names: State Fair Freeway in
Kansas , Chino Valley
Freeway in California,
Rockaway Freeway in New York , and Shenango
Valley Freeway (a portion of US 62 ) in
Unlike in some jurisdictions, not all freeways in the US are part of
a single national freeway network (although together with
non-freeways, they form the National
Highway System). For example,
many state highways such as
California State Route 99 have significant
freeway sections. Many sections of the older

* Arterial routes are designated by two-digit numbers, with
north-south routes having odd numbers, and east-west routes having
even numbers. Primary routes (i.e. major thoroughfares) have 5 or 0 as
their last digit, while secondary routes end in other digits.
* Branch routes have three-digit route numbers, where the first two
digits match the route number of an arterial route. This differs from

Thailand's expressway network, which is the system of usually elevated
expressways within Greater Bangkok. Thailand also has a provincial
The Thai highway network spans over 70,000 kilometres (43,000 mi)
across all regions of Thailand. These highways, however, are often
dual carriageways with frequent u-turn lanes and intersections slowing
down traffic. Coupled with the increase in the number of vehicles and
the demand for a limited-access motorway, the Thai Government issued a
Cabinet resolution in 1997 detailing the motorway construction master
plan. Some upgraded sections of highway are being turned into a
"motorway", while other motorways are being purpose-built.
Although roads are under the responsibility of each individual state,
including en European union, there are some legal conventions
(interntional treaties) and some european directive which give a legal
framework for roads of a european interestwith the goal to introduce
some kind of homogenization between various members. They basically
consider, at European level, three types of roads: motorways, express
roads, and ordinary roads .
Some European treaties also provide some piece of information for
range of speed limit, or for some geometric aspects of roads, for
International E-road network .
A motorway is a road specially designed and built for motor vehicle
traffic, which does not directly provide access to the properties
bordering on it.
Other characteristics of motorways include:
* two separated carriageways for the opposing directions of traffic,
except at special points or, temporarily, due to carriageway repairs
* carriageways that are not crossed at the level of the carriageway
by any other road, railway or tramway track, or footpath; and
* the use of special signposting to indicate the road as a motorway
and to exclude specific categories of road vehicles and/ or road
In determining the extent of a motorway its entry and exit lanes are
included irrespective of the location of the motorway signposts. Urban
motorways are also included in this term.
Motorways status is signaled at the entry and exit of the motorway by
a symbol conforming to international agreements, but specific to each
The peripheral northern and eastern regions of the EU had a lower

where motorways did not exist. There were 26 NUTS level 2 regions with

regions, for instance four overseas French regions and Corsica. The

by the Austrian states since 2002.
Austria currently has 18 autobahns, since 1982 built and maintained
by the self-financed ASFiNAG stock company in Vienna, which is wholly
owned by the Austrian republic and earns revenue from road-user
charges and tolls. Each route bears a number as well as an official
name with local reference, which however is not displayed on road
signs. Unusually for European countries, interchanges (between
motorways called Knoten, "knots") are numbered by distance in
kilometres starting from where the route begins; this arrangement is
also used in the Czech Republic, Slovakia, Hungary, Spain, and most
Canada (and in most American states, albeit in miles).
The current Austrian
Autobahn network has a total length of 1,720 km

In 1937, the first motorway between
completed, following the example of neighboring countries such as
Germany . It mainly served local industries and tourism as a
connection between the capital city and a coastal region. However, the
Second World War
Second World War and the reparation of the complete road network after
the war caused a serious delay in the creation of other motorways. In
1949, the first plans were made to build a complete motorway network
of 930 kilometres (580 mi) that would be integrated with the
neighboring networks. Although the plans were ready, the construction
of the motorway network was much slower than in neighboring countries
because the project was deemed not to be urgent.
Because of economic growth in the 1960s, more citizens could afford
cars, and the call for good-quality roads was higher than ever before.
In each year between 1965 and 1973, over 100 kilometres (62 mi) of
motorway were built. At the end of the 1970s, the construction of
motorways slowed down again due to costs, combined with an economic
crisis, more expensive fuel and changing public opinion. In the
following years, the only investments done were to complete already
started motorway constructions. But most important cities were already
connected. In 1981, the responsibilities for construction and
maintenance of the motorways shifted from the federal to the regional
governments. This sometimes caused tensions between the governments.
For example, the part of the ring road around
Brussels that crosses
Wallonian territory has never been finished, since only Flanders
suffers from the unfinished ring.
Belgium today has the longest total motorway length per area unit of
any country in the world. Most motorway systems in
Belgium have at
least three lanes in each direction. Nearly all motorways have
overhead lighting including those in rural areas. The dense population
Belgium and the still unfinished state of some motorways, such as
the ring roads around
Antwerp cause major traffic
congestion on motorways. On an average Monday morning in 2012, there
was a total of 356 kilometres (221 mi) of traffic jams and the
longest traffic jam of the year was 1,258 kilometres (782 mi), purely
on the motorways.

Highways in Bulgaria
Bulgaria defines two types of highways: motorways
(Aвтомагистрала, Avtomagistrala) and expressways
(Скоростен път, Skorosten pat). The main differences are
that motorways have emergency lanes and the maximum allowed speed
limit is 140 km/h (87 mph), while expressways do not have emergency
lanes and the speed limit is 120 km/h (75 mph). As of January 2016 ,
773 kilometres (480 mi) of motorways are in service, with another 40
kilometres (25 mi) under various stages of construction. More than 100
kilometres (62 mi) are planned. Also, several expressways are planned.

The Czech Republic has currently (2016) 1,247 kilometres (775 mi) of
motorways (dálnice) whose speed limit is 130 km/h or 80 mph (or 80
km/h or 50 mph within a town). The total length should be 2,000
kilometres (1,200 mi) around 2030. The number of a motorway (in red)
copies the number of the national route (in blue) which has been
replaced by the motorway. There are also roads for motorcars (silnice
pro motorová vozidla). Those common roads are not subject to a fee
(in form of vignette) for vehicles with total weight up to 3,5 t and
their high speed limit, if they have divided dual carriageways, may
reach 110 km/h or 70 mph, partially up to 130 km/h or 80 mph.
Motorways in Denmark
Denmark has a well covered motorway system today, which has been
difficult to build due to the county's geography with many islands.
The longest bridges are the Great Belt and the Øresund bridges to
Scania ) in southern Sweden. Both are motorways with dual
electrical train tracks added. A motorway tunnel across the Fehmarn
Germany is planned. Around
Copenhagen , two ring motorways
have been built. Even roads with fewer than 10,000 vehicles per day
have been built in the most northern part of
Jutland . This was done
to assure that all ferry traffic is directed to the motorway system as
soon as possible.
Finland has 863 kilometres (536 mi) of motorway, which is only a
small proportion of the whole highway network. More than half of the
length of the motorway network consists of six radial motorways
Helsinki , to
Tampere (Vt3 /E12 ),
Heinola (Vt4 /E75 ) and Hamina
(Vt7 /E18 ). These roads have a total length of 653 kilometres (406
mi). The other motorways are rather short sections close to the
biggest cities, often designed to be bypasses. The motorway section on
national roads 4 and 29 , between Simo and
Tornio , is said to be the
northernmost motorway in the world.
Finnish motorways do not have a separate road numbering scheme.
Instead, they carry national highway numbers. In addition to
signposted motorways, there are also some limited-access two-lane
expressways , and other grade-separated four-lane expressways (perhaps
the most significant example being
Ring III near Helsinki).

Other shorter sections of motorway either have been or will be built
on some other main routes. In 2007 legislation (the Roads Bill 2007)
was created to allow existing roads be designated motorways by order
because previously legislation allowed only for newly built roads to
be designated motorways.
As a result, most HQDCs nationwide (other than some sections near
Dublin on the N4 and N7 , which did not fully meet motorway standards)
were reclassified as motorways. The first stage in this process
occurred when all the HQDC schemes open or under construction on the

Netherlands Dynamic Route
Information Panel (DRIP) on Dutch A13 freeway during evening rush hour
Roads in the
Netherlands include at least 2,758 kilometres (1,714 mi)
of motorways and expressways , and with a motorway density of 64
kilometres per 1,000 km2 (103 mi/1,000 mi2), the country has one of
the densest motorway networks in the world. About 2,500 kilometres
(1,600 mi) are fully constructed to motorway standards, These are
called Autosnelweg or simply snelweg, and numbered and signposted with
an A and up to three digits, like A12 .
They are consistently built with at least two carriageways , guard
rails and interchanges with grade separation . Since September 2012,
the nationwide maximum speed has been raised to 130 km/h (81 mph), but
on many stretches speed is still limited to 120 or 100 km/h (75 or 62
mph). Dutch motorways may only be used by motor vehicles both capable
and legally allowed to go at least 60 km/h (37 mph).
Dutch roads are used with a very high intensity in relation to the
network length and traffic congestion is common, due to the
country\'s high population density . Therefore, since 1979 large
portions of the motorway network have been equipped with Variable
Message Signs and dynamic electronic signalization, both of which are
aspects of intelligent transportation systems . These signs can show a
lower speed limit, as low as 50 km/h (31 mph), to optimize the flow of
heavy traffic, and a variety of other communications. Additionally
there are peak, rushhour or plus lanes, which allow motorists to use
the hard shoulder as an extra traffic lane in case of congestion.
These extra lanes are observed by CCTV cameras from a traffic control
center. Local and express lanes connected using a basketweave .
Less common, but increasingly, separate roadways are created for
local / regional traffic and long distance traffic. This way the
number of weaving motions across lanes is reduced, and the traffic
capacity per lane of the road is optimised. A special feature of Dutch
motorways is the use of Porous Asphalt
Concrete , which allows water
to drain efficiently, and even in heavy rain no water will splash up,
in contrast to concrete or other road surfaces . The
the only country that uses PAC this extensively, and the goal is to
cover 100% of the motorways with PAC, in spite of the high costs of
construction and maintenance. All in all the
Netherlands has one of
the more advanced motorway networks in the world.
Norway has (2016) 509 kilometres (316 mi) of motorways, in addition
to 427 kilometres (265 mi) of limited-access roads (in Norwegian
motortrafikkvei) where pedestrians, bicycles, etc. are forbidden,
though with a bit lower standard than true motorway. Most of the
network serves the big cities, chiefly
Bergen : see also the
E6, E18 and the E39. Most motorways use four-ramp Dumbbell
interchanges , but also
Roundabout interchanges can be found. The
first motorway was built in 1964, just outside Oslo. The motorways'
road pattern layout is similar to those in the US and Canada,
featuring a yellow stripe towards the median, and white stripes
between the lanes and on the edge. The speed limits are 90–110
kilometres per hour (56–68 mph).

Roads in Portugal
Roads in Portugal
Portugal was the third country in Europe—after
Germany—to build a motorway (Portuguese : autoestrada, plural:
autoestradas), opening, in 1944, the
Estádio Nacional section
of the present A5 (Autoestrada da Costa do Estoril) .
Additional motorway sections were built in the 1960s, 1970s and early
1980s. However, the large-scale building of motorways started only in
the late 1980s. Currently,
Portugal has a very well-developed network
of motorways, with about a 3,000-kilometre (1,900 mi) extension, that
connects all the highly populated coastal regions of the country and
the main cities of the less populous interior. This means that 87% of
the Portuguese population lives at less than 15 minutes' driving time
from a motorway access.
Most of the Portuguese motorways are tolled, although there are also
some non-tolled highways, mostly in urban areas, like those of Greater
Greater Oporto . In the late 1990s and early 2000s, the
Portugal created seven shadow toll concessions, the SCUT
toll (Sem custos para o utilizador, no costs for the user). In those
concessions it were included more than 900 km of motorways and
highways, some of them already built, others which were built in the
following years. However, due to economical and political reasons, the
shadow toll concept was abolished between 2010 and 2011, with
electronic toll equipment being installed in these motorways, to
charge their users. Having only electronic tolls, former SCUT
motorways can now only be used by vehicles equipped with electronic
payment devices or vehicles registered in the system.
Portuguese motorways form an independent network (Rede Nacional de
Motorway Network), that overlaps with the
Fundamental and Complementary subnetworks of the National Highway
Network (Rede Rodoviária Nacional). Each motorway section overlapping
with the Fundamental subnetwork is part of an IP (Itinerário
principal, Principal route) and each motorway section overlapping with
the Complementary subnetwork is part of an IC (Itinerário
complementar, Complementary route). Thus, a motorway can overlap with
sections of different IP or IC routes and - on the other hand - an IP
or IC route can overlap with sections of different motorways. An
example is A22 motorway , which overlaps with sections of IP1 and of
IC4 routes; another example is IP1 route, which overlaps with sections
of the A22, A2 , A12, A1 and A3 motorways.
Motorway Network has a proper numbering system in which
each motorway has a number prefixed by the letter "A". In most cases,
a motorway signage indicates only its A number. The number of the IP
or IC of which a motorway section is a part is not signed except in
some short motorways which lack a proper A number.

expressways, or 771 km in total.
Motorways in Serbia have three lanes (including emergency lane) in
each direction, signs are white-on-green, as in the rest of former
Yugoslavia and the normal speed limit is 120 km/h.
Expressways, unlike motorways, don't have emergency lanes, signs are
white-on-blue and the normal speed limit is 100 km/h.
As the Serbian word for motorway is "autoput", the "A1", "A2" or "A3"
road designations are used since November 2013. All state roads
categorized as class I, that are motorways currently of in the future,
are marked with one-digit numbers and known as class Ia. All other
roads, which belong to class I, are marked with two-digit numbers and
known as class Ib. Expressways belong to class Ib, too. E-numeration
is also widely used on motorways.

Sweden has the largest motorway network in
kilometres, 1,270 mi). It is, however, unevenly allocated. Most
motorways are located in the south of the country, where the
population density is the highest .
The first motorway in
Sweden opened in 1953, between
Lund and Malmö
. Four-lane expressways had been built before, an early example is E20
Alingsås , built in the early 1940s. Most of
the current network was built in the 1970s and 1990s.
"E6 " - The longest motorway (driving forward, not counting routes by
number) begins at the Swedish/Danish border on the
Øresund bridge ,
it then continues along the entire Swedish western coast, up to the
Svinesund bridge which is where
Sweden borders to Norway. It has
several route numbers of which E6 is the overwhelmingly most used one,
in daily speak. Its length is close to 600 km on Swedish territory
alone and it connects four of
Scandinavia 's six largest cities,
Oslo together, as well as
around 20 other more or less notable towns and cities.
A Swedish (partly motorway) route (rather than road) that also has a
significant portion of the Swedish motorway network, is European route
E4 , which runs from the border city of
Scania . E4 is the main route that connects the capital
Scania and the rest of the European continent, via E20
Öresund bridge . All of E4 south of the city
Gävle is of
motorway standard, with only the part passing
Ljungby (32 km) left,
currently in expressway standard. Upgrade to motorway standard will
start in 2017. The part of E4 that runs through western
Essingeleden and is the busiest road in Sweden.
Other highways that have a significant portion of motorway standard
are E20, E18 and E22 . Motorways in
Sweden are however not restricted
to European routes; so called Riksvägar and other regional road types
can also be of motorway standard. An example of this is
Riksväg 40 is the main link between the largest cities in the

Ministry of War Transport in 1946 shortly before the law that
allowed roads to be restricted to specified classes of vehicle (the
Special Roads Act 1949 ) was passed. The first section of motorway,
Preston Bypass , opened in 1958 followed by the first major
section of motorway (the M1 between Crick and Berrygrove in
which opened in 1959. From then until the 1980s, motorways opened at
frequent intervals; by 1972 the first 1,600 kilometres (1,000 mi) of
motorway had been built.
Whilst roads outside of urban areas continued to be built throughout
the 1970s, opposition to urban routes became more pronounced. Most
notably, plans by the
Greater London Council for a series of ringways
were cancelled following extensive road protests and a rise in costs.
In 1986 the single-ring,
M25 motorway was completed as a compromise.
In 1996 the total length of motorways reached 3,200 kilometres (2,000
Motorways in Great Britain, as in numerous European countries, will
nearly always have the following characteristics:
* No traffic lights (except occasionally on slip roads before
reaching the main carriageway).
* Exit is nearly always via a numbered junction and slip road, with
rare minor exceptions.
* Pedestrians, cyclists and vehicles below a specified engine size
* There is a central reservation separating traffic flowing in
opposing directions (the only exception to this is the A38(M) in
Birmingham where the central reservation is replaced by another lane
in which the direction of traffic changes depending on the time of
day. There was another small spur motorway near
Manchester with no
solid central reservation, but this was declassified as a motorway in
* No roundabouts on the main carriageway. (This is only the case on
motorways beginning with M (so called M class)). In the case of
upgraded A roads with numbers ending with M, there are many
roundabouts on the main carriageway. In all M class motorways bar two,
there are no roundabouts except at the point at which the motorway
ends or the motorway designation ends. The only exceptions to this in
Great Britain are:
Southampton which has a roundabout on the main
carriageway where it meets the M27, but then continues as the M271
after the junction. This motorway has been criticised as being
"illegal", and as undermining the meaning of an "M Class" motorway..
* on the M60 . This came about as a result of renumbering sections
of the M62 and M66 motorways near
Manchester as the M60, to form a
ring around the city. What was formerly the junction between the M62
and M66 now involves the clockwise M60 negotiating a roundabout, while
traffic for the eastbound M62 and northbound M66 carries straight on
from the M60. This junction, known as
Simister Island , has also been
criticised for the presence of a roundabout and the numbered route

Unlike many other countries, some of Australia's freeways are being
opened to cyclists. As the respective state governments upgrade their
state's freeways bicycle lanes are being added and/or shoulders
widened alongside the freeways.The state of Queensland is an exception

List of motorways and expressways in New Zealand
New Zealand encompasses multilane divided
freeways as well as narrower 2-4-lane undivided expressways with
varying degrees of grade separation ; the term
Motorway describes the
legal traffic restrictions rather than the type of road.
New Zealand's motorway network is small due to the nation's low
population density and low traffic volumes making it uneconomical to
build controlled-access highways outside the major urban centres.
New Zealand's first motorway opened in December 1950 near Wellington
, running from Johnsonville to Tawa . This five-kilometre (3.1 mi)
motorway now forms the southern part of the Johnsonville-Porirua
Motorway and part of State
Highway 1 . Auckland's first stretch of
motorway was opened in 1953 between Ellerslie and Mount Wellington
(between present-day exit 435 and exit 438), and now forms part of the
Most major urban areas in
New Zealand feature limited-access
motorways, with only
Auckland having a substantial motorway network.

Transport . November 1961. Retrieved 28 December 2007 – via Pathetic
Motorways. Mr Usborne explained that his proposal followed the
principle of the sector system on which trunk and classified roads
were already numbered, although the sectors themselves, which were six
in number, were somewhat different.
* ^ A B Wykes, C. H. (7 July 1959). "How the Motorways Were
Numbered" (Memorandum). Ministry of Transport. Retrieved 28 December
2007 – via Pathetic Motorways. The result of applying such a system
to current plans would be the appropriate numbering of the
Motorway as M1, with provision for extension still
further north as required. M.2 would be reserved for any possible
Channel Ports Motorway, the Medway Towns Bypass meanwhile becoming
A.2(M) and the
Maidstone Bypass A.20(M). M3 would be reserved for a
motorway in the direction of Portsmouth–Southampton, starting with
Exeter Radial. M.4 would be applied to the
South Wales Radial. The
remaining single figure numbers would not be required for radials and
could therefore, continuing clockwise, be applied to the
Birmingham Motorway—M5 and the Penrith–
Dunchurch Bypass—M6. The
Preston Bypass was numbered M6 in advance
and although under these proposals it should initially have been
A6(M), I see no reason to make any change from M.6 pending the
ultimate completion of the whole route.

Numbered" (Memorandum). Ministry of Transport. Retrieved 28 December
2007 – via Pathetic Motorways. Where, however, a motorway is merely
a by-pass along an existing route such as the
Doncaster Bypass along
Route A.1, it will not be given a separate M number, but in order to
make it clear that it is a motorway and that motorway Regulations
apply to it, the letter M will be added in brackets to the existing
route-number: e.g. A.1(M) for the
Doncaster Bypass. This will preserve
the continuity of the route-number of long-distance all-purpose roads.
Generally speaking by-passes that are eventually linked to form a
continuous motorway will preserve the existing route-number (plus M in
brackets) until they are so linked.
