Development Floating Tunnel Tender

Project LocationScope Construction for floating tunnelThe plan includes bridges and the worlds deepest and longest rock tunnel - drilled through bedrock under the seabed - measuring 392 meters 1286 feet deep and 27 kilometers 17 miles long.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.BackgroundWith majestic glaciers fjords and mountains Norway is famous for its dramatic natural landscape.Its rugged terrain does not make traveling easy however. More than 1000 fjords line the Scandinavian countrys west coast which is home to a third of the countrys population of 5.3 million. To make the 1100 kilometer journey between the southern city of Kristiansand and Trondheim in the north via the west coast for example currently takes 21 hours and requires seven ferry crossings.The Norwegian government plans to cut that time by half with a groundbreaking 40 billion infrastructure project to make the route ferry-free.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.A combination of motorways roads and ferry rides E39 runs along the southwestern Norwegian coast. More than 50 of export goods in Norway originate from this area she adds yet the route has a very low standard for a European road. Crossing the fjords via ferry while a popular transport method can be time-consuming.
