Germany
Germany's ''Bundesstraßen'' network has a total length of about 40,000 km.
German ''Bundesstraßen'' are labelled with rectangular yellow signs with black numerals, as opposed to the white-on-blue markers of the ''

controlled-access highway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway, and expressway. Other similar terms ...
s. ''Bundesstraßen'', like autobahns (''Autobahnen''), are maintained by the
federal agency of the
Transport Ministry. In the German highway system they rank below autobahns, but above the ''
Landesstraßen'' and ''
Kreisstraßen'' maintained by the
federal states and the
districts respectively. The numbering was implemented by law in 1932 and has overall been retained up to today, except for those roads located in the
former eastern territories of Germany.
One distinguishing characteristic between German ''Bundesstraßen'' and ''Autobahnen'' is that there usually is a general 100 km/h (62 mph)
speed limit
Speed limits on road traffic, as used in most countries, set the legal maximum speed at which vehicles may travel on a given stretch of road. Speed limits are generally indicated on a traffic sign reflecting the maximum permitted speed, express ...
on federal highways out of
built-up areas, as opposed to the merely advisory speed limit (''
Richtgeschwindigkeit'') of 130 km/h (83 mph) in unmarked sections of the autobahns. However, a number of ''Bundesstraßen'' have been extended as expressways (
dual carriageways) (colloquially called "Yellow Autobahns"), which can be compared to motorway-grade A roads in the U.K. like the
A1(M). Many of these have speed limits of usually 100–120 km/h, others have only an advisory speed limit like autobahns. Most sections of the ''Bundesstraßen'' are only
single carriageway with one lane for each direction and no hard
shoulder pull-out area.

In contrast to Germany, according to a 2002 amendment of the Austrian federal road act, ''Bundesstraßen'' is the official term referring only to
autobahns (''Bundesstraßen A'') and

A limited-access road, known by various terms worldwide, including limited-access highway, partial controlled-access highway, and expressway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a contro ...

federal states (''Bundesländer'').
Therefore, officially classified as ''
Landesstraßen'', they are still colloquially called ''Bundesstraßen'' and have retained their "B" designation (except for

), followed by the number and a name. They are marked by a blue square sign with white number and are per se priority roads.
Before 2002 there has been a further category of ''Bundesstraßen'' with circular yellow sign and black number that shows that this road has no fixed priority (right of way for users). A few yellow signs lived longer than 2002.
Motorway plans
Germany and Austria have plans to reconstruct and/or replace Bundesstraße as/by motorways (Autobahn), outside built-up areas, especially the important ones of 20 to 30 thousands kilometers of the ways in Germany. For Austria they have to replace another 8000 km by schnellstraße/motorways, then Schnellstraße have to be replaced by/rebuilt as motorways.
