Mythe Bridge
River Severn, Tewkesbury, Gloucestershire
associated engineer
Thomas Telford
date  1824 - 12th May 1826
era  Georgian  |  category  Bridge  |  reference  SO887337
ICE reference number  HEW 134
A fine example of Telford's iron bridge work. There had been no previous bridge over the Severn at Tewkesbury, although an unknown architect had drawn up plans for which an Act was obtained in 1823. That bridge was never built, and Telford was contracted to produce a new design at a slightly different site three years later.
Mythe Bridge is a single span of Shropshire iron, measuring 51.8m across. It carries road traffic. On the eastern approach stands a miniature toll-house and on the west, more extensive engineering work involved the construction of an embankment and extended masonry abutments, pierced by narrow arches to lessen resistance against flood water.
The main span is made up of six cast iron arch ribs, each made in eight segments of five X-braced panels. The spandrels have open X-bracing too. The deck is made of cast iron flange plates with solid panel ballast plates. The bridge is 7.3m wide between parapets.
Strengthening work was carried out in 1992. Steel plates were bonded to the overstressed cast iron compressive members using epoxy resin. Additional bracing was also added. These measures enabled the raising of the bridge's weight limit to 17.3 tonnes.
Telford himself considered this bridge to be rather special.
