Norway to build the world's first navigable tunnel under the mountains

Norway has approved a plan to build a 1.7 km long ship tunnel that will run through a mountain range in the northwest of the country.

Coastline outside in the vicinityThe Stadhavet area is the most stormy area in Norway and ships sometimes have to spend several days in the nearest harbor waiting for the weather to improve. Therefore, the Coastal Administration will build a navigable tunnel through the narrowest section of the Stad peninsula.

The budget of the project is about $ 330 million. It provides for the construction of a tunnel 1.7 km long and 36 m wide. The work should begin in 2022 and will take 3-4 years.

The tunnel will be built using underground drilling rigs. For its construction, it will be necessary to extract about 3 million m3 of rock and to dismantle some buildings.

The project should not only simplify transit andmake it safer and also improve business in the region. In the future, it can lead to the creation of a high-speed ferry service.

We also previously reported on the construction of the world's first 10 GW power island in the North Sea.
