Publication Account (2007)
The modern bridge replaced a late-19th century five-span road bridge over the Leven comprising three lattice truss spans and a shorter plate-girder span on each side. This superstructure was supported on cylindrical masonry piers. The view shows work in progress on its recent recon- struction with the girders on one side still in position. The modern bridge utilises the original piers.
The late-19th century bridge replaced an innovative Dredge suspension bridge with a 200 ft main span and
side spans of 45 ft erected in 1841. The calculations for Dredge’s bridge have survived in Weale’s The Theory, Practice and Architecture of Bridges.
