At 4,265 feet deep, the largest in Norway, Sognefjord is too deep to dig a tunnel beneath the sea bottom. The term "floating" is perhaps misleading. Norway’s big idea is as outside of the box as a Star Trek solution: a floating, underwater tunnel. "Route E39 is a key route for Norway," said Kjersti Kvalheim Dunham, a project manager overseeing the revamping of the E39 route. Instead, the plan calls for something the world has never seen before: a submerged floating tunnel. 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. The entire route won't be fully finished until 2050, Kvalheim Dunheim said. A daring piece, but it is not the most ambitious part of the billions plan. Norway starts the largest infrastructure project in its history, in order to better entry to cities across the nordic country. If that succeeds, Norway might be too quick to get rid of rivals like China, South Korea and Italy. The Norwegian Public Roads Administration / Vianova, The Norwegian Public Roads Administration. Norway's landscape, consisting of glaciers, mountains and fjords, is one of the most impressive worldwide. deeper than 1 kilometer (0.6 miles) or wider than 5 kilometers (3 miles). With majestic glaciers, fjords and mountains, Norway is famous for its dramatic natural landscape. Working with the Norwegian navy, the NPRA team is also investigating how the tunnels would fare if submarines crashed into them. In addition, a floating tunnel minimizes the impact on the landscape since most of the infrastructure is out of sight. Rather, it is a submerged floating tube bridgeor SFTB, based on a principle of physics described over 2,000 years ago. Norway May Build an Underwater Tunnel to Ford the Fjords. "Wind, waves and currents have hardly any influence there," Arianna Minoretti, a chief engineer at Norway's Public Roads Administration, told ABC News. The improved E39 will open up more of the west coast to tourism, while the tunnels may become attractions in their own right -- especially if they are a world first. "As a bridge engineer working on this amazing project," says Minoretti, "one can only hope.". But, this spectacular terrain morphology makes travelling a challenging task. ", In fact, she said, "the tunnels may become attractions," like a "new Eiffel Tower on and under the water.". The downward arched submerged floating tunnel (SFT) with no stays is the most economical alternative for free spans up to 1.5 km in deep Norwegian fjords, and in … If successful, Norway could win a global race against countries including China, South Korea and Italy, which are. The proposed tunnel consists of 4,000-foot long concrete tubes that can hold two lanes of traffic. Norway’s $40B infrastructure projectNorway is working on an ambitious infrastructure project to improve the journey between the cities of Kristiansand and Trondheim, which is part of the E39 route crossing the southwestern coast. One planned tunnel will set a world record for a rock tunnel -- drilled under the seabed of a fjord. The Rogfast subsea tunnel is going to be about 27kms-long and 390m deep. The Norwegian government estimates it could cut the drive across the Highway E39 by half the time But the Norwegian government has come up with an ambitious plan, set to cost a whopping $56 billion, to solve the problem. But when the bed is too deep, too rough, the submerged floating tunnel is employed. Norway to achieve "floating tunnel" project-Source: CNN.com Norway plans to invest in floating tunnel technology in order to facilitate motorists' transportation. NPRA is working with the Norwegian University of Science and Technology's Center for Advanced Structural Analysis (CASA), using live explosives to "investigate how tubular concrete structures behave when subjected to internal blast loads," says CASA researcher Martin Kristoffersen. Also called Archimedes’ bridge, the infrastructure designed by Norwegian engineers is based on the thinking of this scientist from Syracuse and brings together the best in bridges with the best in tunnels. It is 684 miles of unending scenery, including rivers and lakes, waterfalls and mountains and numerous fjords. A combination of motorways, roads and ferry rides, E39 runs along the southwestern. The Norwegian Public Roads Administration Waves and currents at 100 feet below sea level are less powerful than those at the surface, explains NPRA's chief engineer Arianna Minoretti. "Norway already has got 1,170 tunnels, 37 of which go under water," explained Kvalheim Dunham. It connects the city of scavenger and Haugesund. This stop-and-start, sea-and-land journey takes 21 hours. The new highway won't be ready anytime soon. Each of the breaks occurs at seven fjords -- where drivers must put their cars on a ferry to get across. Those countries are working on similar projects. Above and Below: The Sognefjorden suspended floating tunnel would be held up by floating platforms, allowing passage of cruise ships (images courtesy of Statens vegvesen). A major highway that connects the city of Kristiansand in the south to Trondheim in the north cuts through a number of fjords. on realising that, when he eased himself into the bath, the same volume of water was displaced. Floating bridges -- structures that are supported by pontoons -- have been built in Norway and the US, among other countries. Floating bridges do not work in all cases because they are susceptible to harsh weather conditions such as strong waves and currents. It also creates less noise than traffic on a bridge would. The submerged-floating road tunnel will allow ships to sail over, while submarines can also pass freely underneath the tunnel. The tunnels are fixed in position with cables -- either anchored to the seabed or tethered to pontoons which are spaced far enough apart to allow boats to pass through. A rendering that shows the floating tunnel anchored to the seabed via cables. More than 1,000 fjords line the Scandinavian country's west coast, which is home to a third of the country's, The Norwegian government plans to cut that time by half with a groundbreaking $40 billion infrastructure project to make the route "ferry-free. Creating "a pleasing driving environment" is just part of the plan for another unique tunnel along the future E39. "Improved transport will improve welfare for the local population, open up to more exports and increase tourism. World's first 'floating tunnel' proposed in Norway The submerged roadway would help speed travel along the nation's rugged west coast. CNN Sans ™ & © 2016 Cable News Network. She said 50 international experts "are doing detailed simulations and detailed measurements of wind speed, current, undersea landslides, bedrock geology, etc." The proposed "floating tunnel" would be the first of its kind. 3rd Symp on Strait Crossings. Three suspension bridges and five floating bridges will be built. Though many countries have shown interest, namely Norway with its very deep fjords, a submerged floating tunnel has never been built. Tveit P. Design of a submerged floating tunnel with a free span on 1750 m. Proc. The tunnel will have two lanes on each side, with passages at every 250m to provide easy exits during emergencies. A floating tunnel obviates those problems---and shouldn't be any more expensive than the saner-sounding, conventional alternatives, the engineers say. It will be 1,286 feet deep and 17 miles long. Beautiful as the land may be, that’s a big nope from us. The plan includes bridges and the world's deepest and longest rock tunnel -- drilled through bedrock under the seabed -- measuring 392 meters (1,286 feet) deep and 27 kilometers (17 miles) long.
