The Skarnsund Bridge ( or ) is a long concrete cable-stayed bridge that crosses the Skarnsundet strait, in the municipality of Inderøy in Trøndelag county, Norway. When finished in 1991, it replaced the Vangshylla–Kjerringvik Ferry and it gives the communities in the municipalities of Mosvik and Leksvik easier access to the central areas of Innherred. The bridge is the only road crossing of the Trondheimsfjord, and is located along Norwegian County Road 755. The bridge has a span of , making it the longest of its type in the world for two years. The two tall pylons are located at Kjerringvik on the west side, and at Vangshylla on the east side. Following the opening, there was a seventeen-year collection of tolls, needed to finance 30% of the investment. In 2007, the bridge was listed as a cultural heritage. In 2012, the municipalities of Mosvik and Inderøy (on either side of the bridge) were merged to form one large municipality of Inderøy. Background Prior to its 2012 merger with Inderøy, Mosvik was a separate municipality on the Fosen peninsula and part of the old Nord-Trøndelag county. The first automotive transport from Mosvik to the more populated area of Innherred commenced in 1958, when the ferry company Innherredsferja started the Levanger–Hokstad–Vangshylla–Kjerringvik–Venneshamn route. In 1964, the road between Kjerringvik and Vennesham, both in Mosvik, opened, and a new ferry was purchased, establishing the Vangshylla–Kjerringvik Ferry. The ferry, and subsequently the bridge, is located at the narrowest section of Skarnsundet, between the villages of Kjerringvik and Vangshylla. In addition to Mosvik, the bridge also caters for the larger municipality Leksvik (now part of Indre Fosen municipality), further out down the fjord. The bridge is the only one to cross the Trondheimsfjord. History The first meeting of local commercial and political interests to establish a bridge was made in 1972. By 1983, it was formalized by the establishment of the company AS Skarnsundsbrua to finance construction. The Parliament of Norway passed the plans in 1986, and construction started two years later. The main contractor was Aker; and after the bridge was finished, maintenance was taken over by the Nord-Trøndelag Public Roads Administration. The bridge cost . The bridge was opened by King Harald V on 19 December 1991, after he had taken the last ferry across the fjord. A monument, the King's Stone, bearing the signature of the king, is located at the resting
