The tunnel was constructed with two parallel immersed tubes with three lanes of traffic in each tube. It is part of the E6 route linking Norway with south-west Sweden.[1] Construction started on 17{{nbsp}}January 1961, and the tunnel was inaugurated at 11:30 am on 29{{nbsp}}March 1968.[1] The tunnel has the lowest motorway elevation in Sweden, at {{convert|15|m|ft|abbr=on}} below sea level (nearby Götatunneln is lower and designed like a motorway but not signposted as one). The tunnel has severe traffic congestion problems since several years, so therefore a new tunnel is built a little farther north, Marieholmstunneln, to be opened in 2020.
