Osterøy Bridge

The Osterøy Bridge (Osterøybrua) is a suspension bridge in Vestland county, Norway. The bridge connects the Kvisti farm area on the island of Osterøy in Osterøy Municipality with the Herland farm area on the mainland in Bergen Municipality east of the city of Bergen. The bridge is the third largest suspension bridge in Norway. It is part of Norwegian County Road 566 (Fylkesvei 566).

The Osterøy Bridge is a 1065 m long suspension bridge that has a main span of 595 m. There are 8 spans, and none of the piers are in the water, just on land. There is 53 m of clearance below the bridge. The two suspension towers are each 121.5 m high. The bridge was completed on 3 October 1997 and cost about NOK308 million. The bridge was designed by the structural engineering firm Aas-Jakobsen. It was put into service 28 years after the first plans for a connection between Osterøy and Bergen were prepared. It was opened for traffic by Sissel Rønbeck, the Norwegian Minister of Transport and Communications. The bridge was built to withstand quite strong winds. Experts have indicated that the bridge should be capable of surviving an extreme storm. The bridge is tuned so that its greatest oscillation occurs when the wind is about 10 m/s such as a light breeze.
