E39 Rogfast is the name given to a possible crossing of Boknafjorden and Kvitsøyfjorden north of Stavanger in the southwestern part of Norway with a sub-sea road-tunnel.

The tunnel starts in Harestad in Randaberg and ends at Arsvågen in Bokn. The tunnels length will be appx. 25,5 km. In addition to the main tunnel there will be an arm up to Kvitsøy with a length of appx. 4 km. E39 Rogfast will be the world’s longest sub-sea road-tunnel. It will also be the deepest sub-sea road-tunnel in the world, the deepest point is appx 385 m beneath the sea level. 

E39 from Stavanger and further north is the main trunkway in the western part of Norway. E39 Rogfast will be a fast and ferryless connection between the two cities Stavanger and Haugesund, and it will also shorten down the travel time between Stavanger and Norways 2nd largest city, Bergen.

We have now started the planning of this project to see whether it is feasible, technical and financial, to develop it. When the plans are ready at the end of 2013 the project will be evaluated. If the results are positive it will be possible to start construction in appx. 2015.
