Skarnsund Bridge ( _no. Skarnsundet bru) connects the municipalities of Mosvik and Inderøy in Nord-Trøndelag in Norway together as part of route 755. The sound Skarnsundet connects Trondheim Fjord with Beitstad Fjord while the bridge connects the regions of Innherred with Fosen.

History

The bridge was opened by King Harald V on December 19 1991 at the picnic stop beside the west foot of the bridge, where one can find "the king stone" with the king's signature.

The ferry connection between Vangshylla on the Inderøy side and Kjerringvik on the Mosvik side was replaced by the bridge. The ferry had hourly departures from each side and was operated by Innherredsferja.

Design

The bridge is one of the world's longest cable-stayed bridges, with a length of 1 010 meters. The span is 530 meters, while the two towers are 152 metes above sea level. It is the longest concrete cable-stayed span. [Walther, Rene et al., "Cable stayed bridges", Thomas Telford Publishing, 2nd edn., 1999, p.18] The sailing height is 45 meters. The bridge was, on its completion, the longest cable-stayed bridge in the world by the length of main span.

The Skarnsund Bridge has won many awards, including "Beautiful Roads Award", "The Road Director's Award", "The Concrete Plate -92" and "FIP Award" (an international concrete award). The original construction work also included 1.6 km of new road. In the construction of the bridge, starting in 1988, 19.600 km³ concrete was used and the 208 cables with a total length of 33 km weigh 1 030 tonnes. The cables have a diameter varying between 52 mm and 85 mm and can, if needed, be replaced separately. The bridge is fundamented in bedrock below the seabed under each tower. The bridge was build to withstand winds up to 48,5 m/s (century storms) and is control calculated for earthquakes.

Financing

In total, the bridge cost 219 million NOK, whereof 30% was to be paid by tolls, which were collected at a toll plaza on the Inderøy side. The company "AS Skarnsundbrua" was incorporated to collect the money, and the final collection of money occurred on May 15 2007.

The final tolls were
* NOK 33 for motor bikes,
* NOK 66 for cars,
* NOK 198 for trucks, and
* NOK 330 for trucks with trailers.
