ABSTRACT
When opened to traffic on 24 October 1961 the Tamar Bridge (Fig. 1), with its 335 m main span, became the longest span road bridge in the UK and 26th equal in the league table for ‘suspension bridges of the world’. Since then it
has been successively relegated in the UK by the Forth, Severn and Humber road bridges, and has disappeared without trace from world rankings.
