North Cape Tunnel

From Wikipedia, the free encyclopedia

North Cape Tunnel or Nordkapptunnelen is a subsea road tunnel under Magerøysundet from the Norwegian mainland to Magerøya. The tunnel was built between 1993 and 1999, is 6,875 metres long, and reaches a depth of 212 metres below the sea level. Before the tunnel was built, a ferry carried the traffic across the sound between Kåfjord and Honningsvåg.

The tunnel takes its name from North Cape at the very north of Magerøya island. North Cape Tunnel is part of European route E69.

The tunnel has anti-freezing gates (Norwegian: Kuldeport) which close the mouths of the tunnel in the winter to avoid freezing of leaking water. These gates open automatically when cars approach and are permanently open in the summer, when traffic is denser.
