Stolma Bridge is a road bridge over the Stolmen sound in Austevoll municipality, Hordaland. It connects the islands Stolmen and Selbjørn. The bridge is 467 meters long and has three spans, the largest of which is 301 meters.
The bridge is a cantilevered prestressed concrete box girder bridge using low density concrete, with a vertical clearance of 30 meters. To achieve its record length for box girder construction, the hollow concrete box girders are 7 meters wide and taper from 15 meters inbox beam depth over the piers to 3.5 meters 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 1.94 tonne/m³. 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.
