Mythe Bridge carries the A438 road across the River Severn at Tewkesbury. It is a cast iron arch bridge spanning 170 feet (52m) and 24 feet (7.3m) wide, designed by Thomas Telford and completed in April 1826. It is a Grade II * listed structure. 〔 (【引用サイトリンク】title= Name: MYTHE BRIDGE List entry Number: 1282810 ) 〕 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 total cost of the bridge including masonry approaches was £14,500, It was originally a toll bridge, but tolls were removed in 1850. Telford wrote: ''I reckon this the most handsomest bridge which has been built under my direction ...'' In 1990 traffic was limited to 7.5 tons, increased to 17 tons after the bridge was strengthened in 1992. == See also == *Crossings of the River Severn *List of bridges in the United Kingdom 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mythe Bridge」の詳細全文を読む スポンサード リンク
