Norway’s European Route E39 is the country’s biggest infrastructure project in its history. Estimated to cost around 50 billion dollars, this coastal highway will connect two sides of Norway and Denmark in a unique fashion. The road consists of underground tunnels, bridges over the sea, and multiple destinations. It is 1,330 km long and one of the longest single roads in the world as well. The project started in 2018 and is still continuing with solid progress. Although one end of the bridge will be in Denmark, the road is fully under the responsibility of the Norwegian Road Administration. The Administration is both constructing the road and the main component in the road’s maintenance.
