Tunnels in Iceland

From Wikipedia, the free encyclopedia

There are eight tunnels in the Icelandic road system (as of September 2005). Tunnels in Iceland are usually built under mountains to prevent winter isolation of remote communities which would otherwise have to depend on high roads that often closed due to snow, to shorten distance between communities, and to increase road-safety by bypassing dangerous stretches of road. A tunnel under a fjord, the Hvalfjörður Tunnel (Hvalfjarðargöng), is among the longest underwater road tunnels in the world [1].
