How much of the world's most complex road will be: Norwegian construction of 1,100 km and 40,000 million US dollars

C & # 39;
a monumental and ambitious project that will cost $ 40 billion and that would be ready by 2050. This is the coastal highway E39 of

Norway

, a road for vehicles that will combine a clbadic roadway with submarine tunnels and 1,100-kilometer floating bridges, according to the BBC.

This motorway, which began to be built recently, is intended to cover a magnificent but impossible geographical route: the thousand fjords of western Norway. E39 will connect the cities of Trondheim in the center of the country and Kristiansand in the south. Normally, this distance takes about 21 hours to cars and trucks that use ferry connections.

The E39 should however reduce this time to 10 hours, in addition to the acceleration of the economy: 57% of Norwegian exports come from the west of the country.

The most ambitious aspect of this project is the development of submerged floating tunnels located about 30 meters below the surface of the water. The tunnels will consist of two parallel concrete cylinders, one for each direction of travel. In turn, each cylinder will have two lanes: one for public transit and one for emergency vehicles and repairs.

If successful, Norway could win a world race against countries like China, South Korea and Italy, which are studying similar projects.

One of the most complex parts will be the link between the islands of Rennesøy and Vestre Bokn, which currently have several submarine bridges and tunnels to other places, but are only interconnected by one service. ferry. The new project involves a 26-kilometer tunnel at depths of nearly 400 meters under the seabed. It will be the longest submarine tunnel in the world and will have an exit halfway to offer citizens of Kvitsøy an alternative route in the form of a gigantic roundabout.

The Norwegian Public Administration (NPRA), the government agency responsible for the project, aims to complete construction by 2050.

The new project of the Government of Oslo begins its first phase and its work will be awarded to different groups with the aim of creating a "seamless" highway. Currently, the E39 has eight different ferries that move people and vehicles through its dangerous waters.

Further north, in the Sognefjord, engineers and architects are considering a simpler option for another fjord nearly 4 km wide with a suspension bridge. In any case, support towers over 450 meters in height would be required for the cables to be suspended.

According to the Government, since environmental and safety laws are the main wake that will guide the project in all its parts, Norway 's vast plan will become a benchmark model for capacity building. engineering and an example for future infrastructure projects in Europe. everybody.
