What You Didn’t Know About Norway's $47 Billion Floating Highway

The Norwegian Public Roads Administration is in the process of creating the world’s first floating highway. The Coastal Highway Route E39 will cut down a 21 hour travel time between the Norwegian cities of Kristiansand in the south and Trondheim in the north by at least half through the elimination of seven different ferry crossings. These crossings will be replaced with bridges, tunnels, and the innovative new Submerged Floating Tube Bridges which give the Coastal road its nickname. But Norway has its work cut out for it, as a project of this size and scale with the use of the floating tunnels has yet to be completed anywhere else in the world-- and attempting the historic roadway project will cost more than $47 billion.
