The Stolma Bridge (Norwegian: Stolmabrua) is a road bridge over the Stolmasundet strait in Austevoll municipality, Hordaland county, Norway. It connects the islands of Stolmen and Selbjørn. The bridge is 467 metres (1,532 ft) long and has three spans, the largest of which is 301 metres (988 ft). The construction cost was US$15.3 million.
The bridge is a cantilevered prestressed concrete box girder bridge using low density concrete, with a vertical clearance of 30 metres (98 ft). To achieve its record length for box girder construction, the hollow concrete box girders are 7 metres (23 ft) wide and taper from 15 metres (49 ft) inbox beam depth over the piers to 3.5 metres (11 ft) in the center of the span. To reduce its weight, the center of the main span is constructed of high-strength low-density concrete with a density of 1,940 kilograms per cubic metre (3,270 pounds per cubic yard). The short end spans which cantilever the main span are ballisted with gravel. The bridge was opened for traffic 14 November 1998 and is part of County Road 151. It was then the world's longest bridge of this type.
