Visit Cantlop Bridge in Shropshire. Discover this 19th-century cast-iron bridge designed by Thomas Telford, a rare survival of early engineering.

A Bridge by Thomas Telford

Cantlop Bridge, near Shrewsbury in Shropshire, is a remarkable survivor from the early 19th century. Built in 1813, it was designed by Thomas Telford, the famous civil engineer responsible for many of Britain’s roads, bridges, and canals.

Carrying traffic across the Cound Brook, it replaced an older timber bridge and showcased the strength and durability of cast iron—a material that would soon dominate the Industrial Revolution.

Engineering Innovation

The bridge is built entirely of cast iron, supported by three ribs with a span of just over 12 metres. Its elegant yet functional design reflects Telford’s skill in adapting iron for civil engineering projects, setting the stage for larger iron bridges across Britain.

Though smaller than the nearby Iron Bridge at Coalbrookdale, Cantlop Bridge demonstrates the continuing evolution of iron bridge design in the early 1800s.

Preservation and Legacy

Cantlop Bridge remained in use for over a century before being closed to vehicles in the 1970s. A modern road bridge now carries traffic alongside, while Telford’s original stands preserved as a historic monument.
