The only bridge in Scotland with single cables over central main supports and was in this respect a precursor of the Millau Viaduct in France. At the time of building it was the longest bridge of its type in the world. A toll bridge until 31 March 2006, and lightly used compared with the M8 Kingston Bridge upstream. The bridge is now part of the trunk road network of Scotland, and is the responsibility of Transport Scotland. One of Scotland's most notorious suicide spots, which has led to the Samaritans  placing signs at each path leading onto the bridge and also within four public telephone boxes that are situated on the twin footpaths running adjacent to the roadway on either side of the river.

Constructor:

The structural engineering was done by Freeman Fox & Partners and the steel fabrication was completed by Fairfields-Mabey. W.A. Fairhurst and Partners (now Fairhurst) designed and oversaw construction of the concrete piers and foundations. Christiani & Nielsen, Lehane Mackenzie and Shand Ltd were the contractors for the foundations and piers. The steel cable supplier was Bridon International. Force Technology were responsible for wind tunnel testing of the bridge. Steel was used to construct the deck and pylons and the piers are made from concrete. The bridge was designed by Dr William Brown (1928–2005), a structural engineer and bridge designer who specialised in suspension bridges. He was one of the principal designers at Freeman Fox & Partners (now Hyder Consulting) from 1956-85. Supervising engineer on the project was Dr Oleg Kerensky and the architect on site was R.E. Slater
