Why are there so many tunnels in Norway?
Norway’s geography is dominated by fjords and islands. As of 2011, the country has thirty-three undersea tunnels, most of which are fixed links. Tunnels are chosen to replace ferries to allow residents of islands and remote peninsulas access to regional centers, where water-crossings are too long for bridges.
