The tunnel takes the European route E69 highway under the Magerøysundet strait between the Norwegian mainland and the large island of Magerøya.

The tunnels were built to connect the mainland of Norway with the town of Honningsvåg and the tourist attraction at the North Cape.

The tunnel is 6.875 kilometres (4.272 mi) long and reaches a depth of 212 metres (696 ft) below sea level.

[1] Before the tunnel was built, a ferry carried the traffic across the sea between the village of Kåfjord and the town of Honningsvåg.

[2][3][4] The tunnel takes its name from the North Cape on the northern shore of Magerøya island.
