Skarnsundbrua is the cable-stayed bridge that carries Fylkesvei 755 over Skarnsundet, the narrow strait between the Fosen peninsula and the Inderøy peninsula in the Trondheimsfjord. It was opened by King Harald V on 19 December 1991, replacing an hourly ferry that ran between Vangshylla on the Inderøy side and Kjerringvik on the Mosvik side.
The main span is 530 metres, total length 1,010 metres, the two A-shaped towers stand 152 metres above sea level, and there are 45 metres of clearance below the deck. At opening it held the world record for the longest main span of any cable-stayed bridge with a concrete deck. France's Pont de Normandie took the record in 1995, but Skarnsundbrua remains Norway's longest cable-stayed bridge and, excluding suspension bridges, Norway's longest bridge span.
The 208 cables carrying the deck have a combined length of 33 kilometres and weigh 1,030 tonnes. The structure was built to withstand gusts up to 48.5 metres per second, a hundred-year storm, and was checked against earthquake loads.
The bridge was tolled until 24 May 2007, paid off almost three years ahead of schedule. Riksantikvaren, the national directorate for cultural heritage, listed it as a protected monument on 17 April 2008, one of very few 20th century bridges with that status. A rest area on the Mosvik side has Kongesteinen, a stone with King Harald V's signature from the opening day.
The crossing is free and takes under a minute. The views over Skarnsundet and the fjord are best from the rest areas at either foot of the bridge.
