The Kyle of Tongue Bridge is part of the Kyle of Tongue Causeway, which crosses Kyle of Tongue sea loch on the north coast of Scotland. The bridge and causeway were built by Sir Alexander Gibb & Partners in 1971 to carry the A838, the road from Thurso to Durness, across the loch. Until 1956 there had been a passenger ferry but the route around the head of the loch involved a narrow road some long. The causeway is long and it crosses a natural island, Tongue Island (Scottish Gaelic: Eilean Thunga). The bridge is at the western end of the causeway and it has eighteen spans supported by twin piers. The bridge was fully refurbished in 2011.
