The world’s longest subsea road tunnel in numbers

Driving under the fjords

The fjords of Norway are beautiful. But they are hindering efficient transportation. Now, the world’s longest and deepest subsea road tunnel will speed things up along the West Coast of Norway.

The high mountains and the narrow inlets, also known as fjords, are Norwegian trademarks. The beautiful landscape along the West Coast of Norway attracts tourists from far and wide.
But for the population, nature can also be hindering. A drive from Trondheim in the north to the southern city of Kristiansand takes a painful 21 hours and requires seven ferry crossings. Now, Norway hopes to cut this drive down to 11 hours by building bridges and tunnels to help travelers across the fjords. The Coastal Highway Route E39 Project is the biggest infrastructure mission in modern Norwegian history and it will all start with a tunnel construction that in itself is a modern-day marvel. The Rogfast tunnel will become the world’s longest and deepest subsea road tunnel.

Here is the tunnel project at a glance:
