Cantlop Bridge is a single span cast-iron road bridge over the Cound Brook, located to the north of Cantlop in the parish of Berrington, Shropshire. It was constructed in 1818 to a design possibly by Thomas Telford, being at least having been approved by him,〔(【引用サイトリンク】title=English heritage Website: Cantlop Bridge )〕 and replaced an unsuccessful cast iron coach bridge constructed in 1812.〔 The design of the bridge was innovative for the period, using a light-weight design of cast-iron lattice ribs to support the road deck in a single span, and appears to be a scaled-down version of a Thomas Telford bridge at Meole Brace, Shropshire. The bridge is the only surviving Telford-approved cast-iron bridge in Shropshire,〔 and is a Grade II listed building and scheduled monument. It originally carried the turnpike road from Shrewsbury to Acton Burnell. ==History and Description== Thomas Telford worked as the County Surveyor of Shropshire between 1787 to 1834, and the bridge is reported to have once held a cast iron plate above the centre of the arch inscribed with ''"Thomas Telford Esqr - Engineer - 1818"'', which is apparently visible in historic photographs, but has not been in place since at least 1985.〔(【引用サイトリンク】title=English Heritage Pastscape website )〕 The bridge design incorporates dressed red and grey sandstone abutments with ashlar dressings, these are slightly curved and ramped, with chamfered ashlar quoins, string courses, and moulded cornices.〔 The structural cast-iron consists of a single segmental span with four arched lattice ribs, braced by five transverse cast-ironmembers. The road deck is formed from cast-iron metal deck plates, tarmacked over, and now finished with gravel. The original parapets have at some point been replaced with painted cast-iron railings with dograils, dogbars and shaped end balusters.〔
