Causey Arch

The Causey Arch stands near Stanley in County Durham, a single-arch railway bridge built in the 1720s. It once carried a wagonway that moved coal from Dawson’s Colliery to the River Tyne. The bridge was the longest of its kind when finished, with an arch of 31 metres. Ralph Wood built it for a group of coal owners called the Grand Allies. After its completion, Wood took his own life, fearing the bridge would collapse. The arch carried over 900 horse-drawn wagons each day before a fire at Tanfield Colliery reduced its use. It was later bypassed when the railway line was diverted. The bridge remains the oldest surviving single-arch railway bridge in the world. An inscription on a sundial marks Wood’s work and the year 1727. Today the arch is Grade I listed and surrounded by scenic paths beside Causey Burn. The burn flows into Beamish Burn and then the River Team, which meets the River Tyne downstream. Quarries nearby attract rock climbers, and the area offers walking routes for visitors. The bridge’s industrial past is still visible in the landscape.
