The causeway across the Kyle of Tongue was built in 1971 to cut out a 6 or 7 mile detour around the southern end of the Kyle. The approach to the causeway from Tongue utilises pre-existing roads, albeit with a little re alignment, and then stretches out across a long spit of land over the sands. The causeway is built on a sweeping curve to make the most of the natural landscape of the Kyle. This sees a former island used to provide a small car park and picnic site just before the bridge across the main channel.
The bridge consists of 18 spans, each supported by twin piers into the river, and carries an S2 roadway. It was completely refurbished in 2011 to ensure that it maintains this important link for another 30 or 40 years.
