Norway will spend billions on floating underwater tunnels

Norway's beautiful landscape surrounded by endless fjords draws tourists from all over the world. For locals, however, the vast expanses of water that cut through the country's coastal areas are a road traffic nightmare.

Currently, the only way to get across them is by taking ferries, which are slow and frustrating. To combat this, the Norwegian government has hatched an ambitious plan to build underwater tunnels suspended from floating pontoons.
