"Wind, waves and currents have hardly any influence there," Arianna Minoretti, a chief engineer at Norway's Public Roads Administration, told ABC News. 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 proposed "floating tunnel" would be the first of its kind. Archimedes supposedly criedEureka! Norway is building the world's first submerged floating tunnel to cross the fjords. "Improved transport will improve welfare for the local population, open up to more exports and increase tourism. CNN Sans ™ & © 2016 Cable News Network. Seven times the change of missing it or having to wait for seven ferries. The Norwegian government are embarking on the largest infrastructure project in the country's history. If successful, Norway could win a global race against countries including China, South Korea and Italy, which are. A rendering that shows the floating tunnel anchored to the seabed via cables. It connects the city of scavenger and Haugesund. But, this spectacular terrain morphology makes travelling a challenging task. Instead, the plan calls for something the world has never seen before: a submerged floating tunnel. This stop-and-start, sea-and-land journey takes 21 hours. Highway E39 in Norway is one of the most beautiful drives in the world, hugging the country's rugged west coast from Kristiansand to Trondheim. The Norwegian government estimates it could cut the drive across the Highway E39 by half the time to make sure the plans, as well as the tunnel, is rooted in "the real-world environment.". Floating bridges do not work in all cases because they are susceptible to harsh weather conditions such as strong waves and currents. 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. The submerged-floating road tunnel will allow ships to sail over, while submarines can also pass freely underneath the tunnel. 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. A floating tunnel obviates those problems---and shouldn't be any more expensive than the saner-sounding, conventional alternatives, the engineers say. This is where the floating tunnels come in. It also creates less noise than traffic on a bridge would. E39 Rogfast will be a twin-tube road tunnel, which will cross Boknafjorden and Kvitsøyfjorden north of Stavanger, replacing the current ferry over Boknafjorden. I n a world first, Norway is planning to build a submerged, floating tunnel to allow road traffic to cross one of its deepest fjords. It is 684 miles of unending scenery, including rivers and lakes, waterfalls and mountains and numerous fjords. Turn on desktop notifications for breaking stories about interest? 3rd Symp on Strait Crossings. When a fjord is deeper than 1 kilometer (0.6 miles) or wider than 5 kilometers (3 miles), however, existing engineering solutions are not going to cut it. Norway has hatched ambitious plans to install the world’s first floating underwater tunnels to help travelers easily cross the nation’s many fjords. The new highway won't be ready anytime soon. Three suspension bridges and five floating bridges will be built. At 4,265 feet deep, the largest in Norway, Sognefjord is too deep to dig a tunnel beneath the sea bottom. The Norwegian Public Roads Administration (NPRA), the governmental body responsible for the project, aims to complete construction by 2050. The Norwegian Public Roads Administration A rendering of a submerged floating tunnel under the surface of the water. But the Norwegian government thinks it can reduce the drive time by half, with its ambitious plan for the world's first submerged floating tunnel. Is it a tunnel, is it a bridge? A major highway that connects the city of Kristiansand in the south to Trondheim in the north cuts through a number of fjords. It is predicted to cost $25 billion (around £19 million) to build, according to Wired. Norway is planning to construct a submerged floating bridge to help travelers easily cross seven of the country's fjords. If that succeeds, Norway might be too quick to get rid of rivals like China, South Korea and Italy. That honour goes to the “floating” tunnel about 30 meters below sea level. With majestic glaciers, fjords and mountains, Norway is famous for its dramatic natural landscape. An illustration shows what a potential underwater floating tunnel, with tubes for traffic going both ways, would look like in Norway. Made of concrete, they would function like conventional tunnels, transporting vehicles from one end of a fjord to another. Can Norway win the global race to build a 'floating tunnel'? To make that drive easier, the Norwegian Public Roads Administration (NPRA) has proposed the world's first underwater floating tunnel, which would be submerged in the Norwegian Sea. By 2025, 33 percent of the project is expected to be completed. It also creates less noise than traffic on a bridge would. She said 50 international experts "are doing detailed simulations and detailed measurements of wind speed, current, undersea landslides, bedrock geology, etc." A combination of motorways, roads and ferry rides, E39 runs along the southwestern. But if you look carefully at a road map, E39 is something of a dotted line. It will be 1,286 feet deep and 17 miles long. Though many countries have shown interest, namely Norway with its very deep fjords, a submerged floating tunnel has never been built. As of 2016 , a submerged floating tunnel has never been built, but several proposals have been floated by different entities. Norway to achieve "floating tunnel" project-Source: CNN.com Norway plans to invest in floating tunnel technology in order to facilitate motorists' transportation. The proposed tunnel consists of 4,000-foot long concrete tubes that can hold two lanes of traffic. The tunnel will have two lanes on each side, with passages at every 250m to provide easy exits during emergencies. Floating bridges -- structures that are supported by pontoons -- have been built in Norway and the US, among other countries. Working with the Norwegian navy, the NPRA team is also investigating how the tunnels would fare if submarines crashed into them. Creating "a pleasing driving environment" is just part of the plan for another unique tunnel along the future E39. While locations for the submerged floating tunnels have not yet been pinned down, Minoretti says the. The entire route won't be fully finished until 2050, Kvalheim Dunheim said. ... Norway’s public roads administration has proposed building the world’s first “submerged floating tunnels” along E39. In addition to staying clear of water traffic, the depth of the tunnel assures smooth driving. "That would be an advantage ... (for) people living in the area," Minoretti says. But the most ambitious aspect is the development of submerged floating tunnels that sit around 30 meters (100 feet) under the surface of the water. The government intends to improve transport "for commercial purposes (and) also for the welfare of the local population," Dunham says. 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. "Norwegians are quite used to going under water in tunnels.". 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). Norway May Build an Underwater Tunnel to Ford the Fjords. 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. The Norwegian Public Roads Administration Although not much is known about his li… To date, 10 percent of the project has been completed. Each of the breaks occurs at seven fjords -- where drivers must put their cars on a ferry to get across. Instead, the plan calls for something the world has never seen before: a submerged floating tunnel. Norway Public Roads Administration programme manager Kjersti Kvalheim Dunham told The Telegraph: “It’s nearly 1,100km from end to end, but the journey takes 21 hours on a good day, because of the seven ferry crossings en route. "Norway already has got 1,170 tunnels, 37 of which go under water," explained Kvalheim Dunham. These next-level underwater villas are making waves. Its rugged terrain does not make traveling easy, however. 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. Not just any tunnel either. Catch up on the developing stories making headlines today. Tveit P. Design of a submerged floating tunnel with a free span on 1750 m. Proc. that means seven ferry trips. The journey between Kristiansand and Trondheim is part of the E39, which is a "key route for Norway," explains Kjersti Kvalheim Dunham, a project manager at NPRA. The biggest risks in the project are explosions, fire and overloading, says Minoretti -- and so extensive testing is essential. This is what the floating bridge would look like. The twin tunnels will have a diameter of 10.5m and a maximum depth of 392m below sea level. The two concrete tubes of the tunnel -- one for traffic headed in each direction -- will be firmly fixed in position and attached to floating pontoons, spaced 820 feet apart to allow sea vessels to pass through. An illustration shows a potential submerged floating tunnel (SFT), as it would show on the surface, to cross a fjord in Norway. "Route E39 is a key route for Norway," said Kjersti Kvalheim Dunham, a project manager overseeing the revamping of the E39 route. The idea for a submerged floating tunnel is not new. Norway starts the largest infrastructure project in its history, in order to better entry to cities across the nordic country. Those countries are working on similar projects. 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 is proposing a multiple-lane national highway that could reduce cross-country travel time from 21 hours down to about 11. The tests will help the team to understand what would happen to the tunnel's structure if, for example, a truck carrying dangerous goods exploded inside. 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 … Norway, the Scandinavian country that isn't Finland or Sweden, is considering an unprecedented civil engineering project that will involve floating … Tunnel, with tubes for traffic going both ways, would look like in Norway norway floating tunnel Sognefjord too...
