E39 Eiganestunnel
Norway
The Eiganes Tunnel will significantly reduce the volume of traffic in Stavanger's city centre and also improve the connection between the inner city and the existing Ryfast Tunnel. Along with a tunnel forming wagon for the north and south portals, Doka also supplied a formwork solution with which the three different tunnel cross-sections could be constructed with only one forming carriage and a minimum of alterations.
