The Kristiansund Mainland Connection (Norwegian: Kristiansund fastlandsforbindelse or abbreviated Krifast) is a road system consisting of the European route E39 highway and Norwegian National Road 70 that connects Kristiansund Municipality to the neighboring islands of Frei, Bergsøya, and Aspøya and then to the mainland of Norway.
The bridge is supported by 7 pontoons, floating on a 320-metre (1,050 ft) deep fjord.
Krifast was authorized by the Norwegian Parliament and construction began in October 1988.
As of July 1991, the project employed 427 people, and spent 2 million kr daily on construction.
Four years and NOK 1.1 billion later, in August 1992, Krifast was opened for regular traffic.
