Building below sea level
AF Gruppen is general contractor for contract E03 Ryfast, which comprises the construction of a 6.3 km twin-bore tunnel, surface zones with local roads, four portal structures, a 100-metre bridge and buildings for technical systems at surface level and in the tunnel. The Ryfylke Tunnel was at the time of completion the longest subsea tunnel in the world for ordinary road traffic, with a total length of 14.3 kilometres.
The tunnel was built from both ends, with one contractor at each end. The tunnel bores met 292 metres under the sea.
For safety reasons, the tunnels in the Ryfast project were constructed as twin-bore tunnels, with two lanes in each direction.
AF has also previously constructed subsea tunnels, and possesses the expertise, capacity and competitive ability to undertake major subsea projects. Production of tunnels and caverns for hydroelectric power, road and rail projects, as well as other subsea projects for industrial purposes are carried out by AF Anlegg.
