Mythe Bridge

About

Mythe Bridge carries the A438 road across the River Severn at Tewkesbury. It is a cast-iron arch bridge spanning 170 feet (52 m) and 24 feet (7.3 m) wide, designed by Thomas Telford and completed in April 1826. It is a Grade II* listed structure.

With authorisation given by the Tewkesbury Severn Bridge and Roads Act 1823 (4 Geo. 4. c.

ii), Telford was appointed to design the bridge in 1823, following a dispute between the bridge trustees and their existing architect, who had proposed a bridge with three shorter iron arches. Telford changed the scheme to a single span so as to reduce interference with navigation of the river, and also to eliminate the expense of constructing foundations in the river gravels. Like Telford's Craigellachie Bridge, Mythe Bridge was cast by William Hazledine, and is similar in form to Telford's Galton Bridge, which spans the Birmingham Canal at Smethwick.

It has six cast iron ribs, each cast in 23-foot (7m) lengths, with spandrels filled with X-shaped bracing. Telford described the iron as "best Shropshire iron, commonly called No. 2"'.

The arch rises 17 feet (5.2m), one tenth of the span. The X-bracing carries the diagonal crossed bracing to the spandrels...
