It is the longest road tunnel in the world, and carries two lanes of European Route E16, the main road between Oslo and Bergen. In 1975, the Parliament of Norway decided that the main road between Oslo and Bergen would run via Filefjell, and in 1992 passed legislation to build the tunnel. Construction started in 1995, and the tunnel opened in 2000. It cost 1,082 million Norwegian krone, although unlike most tunnels in Norway was not subject to tolls.
