A tunnel under water – how do you build that? How a colossal elevator could revolutionize space travel. It includes the name, length in meters and feet, depth below mean sea level in meters and feet, the year the tunnel was taken into use with ordinary traffic (which may differ from the year it was officially opened), the road the tunnel carries, the county or counties the tunnel is in, and the municipalities, including any the tunnel passes through. As was the case in most of Europe, which revolved around industry and mechanisation, the country embarked upon more than five decades of track construction to connect its complicated geography. Most of the tunnels are built as fixed links, allowing ferry services to be abandoned. Project which have been abandoned or have not been subject to public investigations are not included. The Coastal Highway Route E39 Project is the biggest infrastructure mission in modern Norwegian history and it will all start with a tunnel construction that in itself is a modern-day marvel. Roads starting with E indicates a European route, while FV indicates a county road without signposted road number; only numbers indicates roadside-numbered county roads which are former national roads.[2].

For the authorities, decision for new tunnels depends on the length, possibility to build a bridge, depth of the sound or fjord and population in the affected areas. The Bømlafjord Tunnel is the country's longest, at 7,888 meters (25,879 ft). Conventional cable-stayed bridges and tunnels won't work in parts of Norway's west coast because some of the fjords are simply too deep. Shopping. “We have done simulations for big explosions in the tunnel, we’ve checked for impacts of submarines, we covered scenarios where a trawler might hook onto the tunnel, and we even considered if a ship might be sinking at the surface and hit the tunnel on the way down,” Rønnquist said. Up Next. THE PROJECT “With bridges that span long distances, you need arches and suspensions at certain points, but for a submerged floating tunnel, if you do it absolutely correct and balance the weight of the structure with the buoyancy of the structure, it can go on forever,” said Nils Erik Anders Rønnquist, a professor of structural engineering at the Norwegian University of Science and Technology, who is consulting on the project for the government. The tunnel will stretch for 27km at a depth of up to 392m below the sea, and cut the road travel time between the southwest coastal cities of Bergen and Stavanger from five hours to 40 minutes. The mile-long, 36-metre-wide wide tunnel … Norway's geography is dominated by fjords and islands. Most of the tunnels are built as fixed links, … Europe Norway Facts - Worlds longest tunnel, the laerdal tunnel, outside Author: Arne Brekke, Brekke Tours. It is located 48m below mean sea level between Mainland South Korea and Geoje Island. The proposed "floating tunnel" would be the first of its kind. The following tunnels are under construction, but are not yet completed or taken into use. Norway's Government has approved a colossal engineering project to build the first marine tunnel under the mountains of Stad, a little peninsula bathed by the Norwegian Sea, characterized by high wind speed and its harsh weather conditions. It is part of the “ferry-free Vestland” plan, however there is no guarantee that ferry services will be put out of … The lowest point of the tunnel network is 187m (613ft) below sea level. A first scheme, the Ryfast will feature three tunnels including a 14.3km long link that plunges to 290m, deeper beneath the sea than any tunnel before. Though the floating tunnel is buoyant, it isn’t actually floating. The 7.8 kilometres long tunnel reaches 260.4 m (854 ft) below mean sea level, according to Wikipedia. Share.
