List of subsea tunnels in Norway : ウィキペディア英語版 | List of subsea tunnels in Norway Norway's geography is dominated by fjords and islands. As of 2011, the country has 33 undersea tunnels, most of which are fixed links. Tunnels are chosen to replace ferrys to allow residents of islands and sealocked peninsulas access to regional centers, where crossing are too long for bridges. The Bømlafjord Tunnel is the country's longest, at , although it is scheduled to be surpassed by the Karmøy Tunnel from 2013. The Eiksund Tunnel is the world's deepest, reaching below mean sea level. In 1982, The Vardø Tunnel was the first underwater tunnel to open. Most of the tunnels are built as fixed links, allowing ferry services to be abandoned. In 2010, the first three tunnel in cities, the Bjørvika Tunnel, the Skansen Tunnel and the Knappe Tunnel, were opened, all which were built as motorways to bypass the city center. Submerged floating tunnels have previously been proposed; as they do not need to be built under a fjord, they allow for tunnels to be built in places too deep for conventional tunnels, such as for crossing Sognefjord. ==Current== The following lists all subsea tunnels in use as of 2011. It includes the name, length in meters and feet, depth below mean sea level in meters and feet, the year the tunnel was taken into use with ordinary traffic (which may differ from the year it was officially opened), the road the tunnel carries, the county or counties the tunnel is in, and the municipalities, including any the tunnel passes through. Roads starting with E indicates a European route, while FV indicates a county road without signposted road number; only numbers indicates roadside-numbered county roads which are former national roads.
