Construction

The 467 m long and 9.0 m wide reinforced concrete structure has three spans. The spans amount to 94 m on the shore of the island Selbjørn and 72 m on the shore of the island Stolmen. The main opening spans 301 meters and was built by the balanced cantilever. The bridge cross section consists of a 7.0 m wide hollow box whose height varies between 3.5 m and 15.0 m in middle of the bridge over the piers. To reduce the superstructure dead weight came to a length of 184 m in the center of the main opening, a light-weight concrete of strength class LC 60 with a bulk density of 1.94 kg / dm ³ apply. The main span in relation to the relatively short fringe fields are also ballasted with gravel.
