Elbe Tunnel (1975)
The New Elbe Tunnel (), often simply called ''Elbtunnel'', is a subterranean Elbe River crossing in northern Germany located in Hamburg. Description The Elbtunnel has a length of . As a part of the Bundesautobahn 7 in Hamburg, the tunnel forms a connection between Schleswig-Holstein (and on towards Denmark) to the north and Lower Saxony to the south. It has 8 lanes in 4 bores. The newest, fourth bore is the only one to feature a hard shoulder, minimizing congestion due to broken down vehicles. Parts of the tunnel are 27 metres below the water line. History The tunnel was constructed from 1968 to 1975 with three bores, containing a total of six autobahn lanes serving the city of Hamburg. On 10 January 1975 the Chancellor of Germany, Helmut Schmidt, opened the Elbe Tunnel. The tunnel was constructed with a capacity for 65,000 cars daily. In 1989 concrete tank barriers were constructed on the three south entrances. In war times these barriers would have been exploded out of thei ...

Bundesautobahn 7
is the longest German Autobahn and the longest national motorway in Europe at 963 km (598 mi). It bisects the country almost evenly between east and west. In the north, it starts at the border with Denmark as an extension of the Danish part of E45. In the south, the autobahn ends at the Austrian border. This final gap was closed in September 2009. Overview The Bundesautobahn 7 starts at Flensburg and travels through the two states at Schleswig and Rendsburg, through the world's busiest artificial waterway of Kiel Canal crossing the Rader high bridge. At Rendsburg you can change to the A 210, a feeder to the Schleswig-Holstein capital, Kiel. A few kilometers further south there is another feeder route to Kiel, the A 215, into the A7 at the interchange Bordesholm; however, this can only be reached from the south, likewise from the A 215 you can only reach the A7 in the south. South of Bordesholm, the highway has been continuously expanded to six lanes since 2014 due to the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldecott Tunnel
The Caldecott Tunnel is a four-bore highway tunnel through the Berkeley Hills between Oakland and Orinda, California. Its four bores carry California State Route 24. Named after Thomas E. Caldecott, former mayor of Berkeley, it opened in 1937 as a two-bore tunnel. The third bore opened in 1964 and the fourth bore in 2013. Currently, the two oldest bores carry eastbound traffic and the two newest bores carry westbound traffic. Description The east–west tunnel is signed as a part of California State Route 24 and connects Oakland to central Contra Costa County. It is named after Thomas E. Caldecott (1878–1951), who was mayor of Berkeley in 1930–1932, a member of the Alameda County Board of Supervisors in 1933–1945, and president of Joint Highway District 13, which built the first two bores. Bore 1 (the southernmost bore) and Bore 2 were completed in 1937; they are in length and today carry two lanes each of eastbound traffic. Bore 3, completed in 1964, is in leng ...

Roads With A Reversible Lane
A road is a thoroughfare used primarily for movement of traffic. Roads differ from streets, whose primary use is local access. They also differ from stroads, which combine the features of streets and roads. Most modern roads are paved. The words "road" and "street" are commonly considered to be interchangeable, but the distinction is important in urban design. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically, many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized ...

Tunnels Completed In 1975
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two Portal (architecture), portals common at each end, though there may be access and ventilation openings at various points along the length. A Pipeline transport, pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail transport, rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sanitary sewer, sewers or aqueduct (watercourse), aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passa ...

Old Elbe Tunnel
Old Elbe Tunnel or St. Pauli Elbe Tunnel (German: ''Alter Elbtunnel'' colloquially or ''St. Pauli Elbtunnel'' officially), which opened in 1911, is a pedestrian and vehicle tunnel in Hamburg. The 426 m (1,398 ft) long tunnel was a technical sensation; 24 m (80 ft) beneath the surface, two 6 m (20 ft) diameter tubes connect central Hamburg with the docks and shipyards on the south side of the river Elbe. This was a big improvement for tens of thousands of workers in one of the busiest harbors in the world. Six large lifts on either side of the tunnel carry pedestrians and vehicles to the bottom. The two tunnels are both still in operation, though due to their limited capacity by today's standards, other bridges and tunnels have been built and taken over most of the traffic. In 2008 approximately 300,000 cars, 63,000 bicycles, and 700,000 pedestrians used the tunnel. The tunnel is opened 24 hours for pedestrians and bicycles; however, as of October 2023, the tunnel is closed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oversize Load
In road transport, an oversize load (or overweight load) is a load that exceeds the standard or ordinary legal size and/or weight limits for a truck to convey on a specified portion of road, highway, or other transport infrastructure, such as air freight or water freight. In Europe, it may be referred to as special transport or heavy and oversized transportation. There may also be load-per-axle limits. However, a load that exceeds the per-axle limits but not the overall weight limits is considered overweight. Examples of oversize/overweight loads include construction machines (cranes, front loaders, backhoes, etc.), pre-built homes, containers, and construction elements (bridge beams, generators, windmill propellers, rocket stages, and industrial equipment). Overview The legal dimensions and weights vary between countries and regions within a country. A vehicle which exceeds the legal dimensions usually requires a special permit which requires extra fees to be paid in order for ...

Traffic Light
Traffic lights, traffic signals, or stoplights – also known as robots in South Africa, Zambia, and Namibia – are signaling devices positioned at intersection (road), road intersections, pedestrian crossings, and other locations in order to control the flow of traffic. Traffic lights usually consist of three signals, transmitting meaningful information to road users through colours and symbols, including arrows and bicycles. The usual traffic light colours are red to stop traffic, Amber (color), amber for traffic change, and green to allow traffic to proceed. These are arranged vertically or horizontally in that order. Although this is internationally standardised, variations in traffic light sequences and laws exist on national and local scales. Traffic lights were first introduced in December 1868 on Parliament Square in London to reduce the need for police officers to control traffic. Since then, electricity and computerised control have advanced traffic light technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
