Norway is famous not only for its dramatic natural landscape, but with its ambitious projects as well.
The Norwegian government plans to cut that time taken for the 1,100 kilometer journey between the southern city of Kristiansand and Trondheim in the north via the west coast by half with a $40 billion infrastructure project to make the route “ferry-free.” It takes more than 21 hours to have such journey now.
The plan includes bridges and the world’s deepest and longest rock tunnel. According to the reports, this tunnel measures 392 meters (1,286 feet) deep and 27 kilometers (17 miles) long.
The most interesting and ambitious part of the project is that that sit around 30 meters under the surface of the water.
If successful, Norway could win a global race against countries including China, South Korea and Italy, which are researching similar projects.
The government intends to improve transport “for commercial purposes (and) also for the welfare of the local population,” Kjersti Kvalheim Dunham, a project manager at NPRA, says.
The idea for a floating tunnel is not new. It was developed in 1882 by British naval architect Edward Reed which was aimed to cross the English Channel. But that proposal was vetoed.
The term “floating” is perhaps misleading. The tunnels are fixed in position with cables. However, the biggest risks in the project are explosions, fire and overloading. Thus extensive testings are so essential.
