Cantlop Bridge is a single span cast-iron road bridge over Cound Brook 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,[1] and replaced an unsuccessful cast iron coach bridge constructed in 1812.[2] 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,[1] and is a Grade II listed building and scheduled monument.

History and Description[edit]

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.[2] 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.[2] 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.[2]

The bridge today remains as a monument only, being closed to normal traffic. It was bypassed by a more modern adjacent concrete bridge built in the 1970s. It is in the care of English Heritage and is freely accessible from a nearby layby.
