Norway will build the world’s first underwater floating transport tunnel


The Norwegian government began to implement the construction project of the world’s first underwater floating transport tunnel along the West Coast, which will double the trip time along the E39 highway.

Although this route opens beautiful views of the coast and fjords, but the road takes 21 hours. Therefore, the management of public roads conducted a study and found that the main delays are associated with the ferry ferry. As a result, various solutions were proposed to reduce time on the way, some of which involves the creation of underwater floating tubular bridges between several fjords.

Underwater tunnels will be different lengths, and the length of the largest will be about 5 km. Although the advanced idea is not new and was set forth in the Sea architect Edward Reed in 1882, but this structure will be implemented for the first time in practice. Pipes will be at a depth of 20 meters so as not to interfere with the movement of ships and attached to pontions, the distance between which will reach 400 m in some areas. In addition to cars, cyclists and pedestrians will be able to move.

According to representatives of the Road Department of Norway, the engineers have long studied this option, but now it has become possible due to the presence of sufficient experience in the construction of marine and oil structures. They also took into account the possibility of movement of submarines and other features of operation.

The first sections are planning to put into operation in about a year. At the same time, the existing roads will be preserved, so those who want to admire the nature will be able to enjoy the trip, as before, and those who are in a hurry will be able to use the new route.
