Cantlop Bridge

Cantlop Bridge is a single-span cast-iron road bridge over the Cound Brook, just north of the village of Cantlop in the parish of Berrington, Shropshire. It is one of the most interesting survivals of the early Industrial Revolution in a county often called the birthplace of cast-iron engineering.

What makes this bridge special?

It is the only surviving cast-iron bridge in Shropshire approved by Thomas Telford, the celebrated Scottish civil engineer. It is a Grade II* listed building and a scheduled monument, a high level of protection that reflects how valuable this modest crossing is.

The design was innovative for its time. Light cast-iron lattice ribs carry the road deck in one clear span over the brook, so the stream meets no pier in mid-channel. The result is a slim, elegant structure that looks like a scaled-down version of Telford's bridge at Meole Brace, also in Shropshire.

Who designed it?

Authorship of the design is not fully settled. The bridge follows a design approved by Telford. The castings were supplied by William Hazeldine, a well-known ironmaster in the region, according to heritage records.

When was it built?

Sources give different dates. The most common account says the present bridge dates to 1818 and replaced an unsuccessful cast-iron coach bridge built in 1812. Some accounts, including English Heritage material, link the bridge to 1813. Whichever date you prefer, the story shows that early experiments with iron did not always succeed, and engineers learned as they went.

What was it for?

The bridge originally carried the turnpike road from Shrewsbury to Acton Burnell, part of a wider effort to improve roads and trade across Shropshire.

What does it look like today?

Cracks in one of the arch ribs led to a weight restriction in 1974. A new concrete bridge was built to the west and Cantlop Bridge was closed to vehicles. That decision preserved the older structure almost as built. The span measures roughly 9.5 metres, with the deck resting on four parallel arched ribs and five cast-iron cross members.

Frequently asked questions

Can I walk onto the bridge? Yes, it is accessible on foot, with the approach running alongside the modern bridge that now takes the traffic.

Is there an entry fee? No. The site, looked after by English Heritage, is free and open at any reasonable time during daylight hours.

Where exactly is it? Near the village of Cantlop, not far from Shrewsbury, postcode SY5 7DD, over the Cound Brook.

Who is it for? Fans of industrial heritage, engineering and the work of Thomas Telford. It makes a short stop, best combined with exploring the countryside around Shrewsbury and other sites tied to Shropshire's early ironworking.

How long should I allow? Looking over the deck, checking the lattice ribs from the side and taking a short stroll along the brook usually takes anything from a quarter of an hour to under an hour.

Cantlop Bridge is not a headline attraction, but it is a rewarding stop for the curious: quiet, well preserved and unique within the county.
