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. The Ryfylke Tunnel is the country's longest, at 14,400 meters (47,200 ft).
The Ryfylke Tunnel is the world's deepest, reaching 292 meters (958 ft) below mean sea level. Norway's first subsea tunnel was the Vardø Tunnel, which opened in 1982. Most of the tunnels are built as fixed links, allowing ferry services to be abandoned. In 2010, the first three tunnels in cities, the Bjørvika Tunnel, the Skansen Tunnel and the Knappe Tunnel, were opened, all of which were built as motorways to bypass the city center. Suspended tunnels have been proposed, which could be installed in places too deep for conventional tunnels, such as the Sognefjord.[1][needs update?]
