Norway to Build first Floating Tunnel

With majestic glaciers, fjords and mountains, Norway is famous for its dramatic natural landscape. Its rugged terrain does not make traveling easy, however. More than 1,000 fjords line the Scandinavian country’s west coast, which is home to a third of the country’s population of 5.3 million. To make the 1,100 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 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.

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.
