Causey Arch, Stanley

About:

Causey Arch, located near Stanley in County Durham, England, is a historic railway bridge and an important monument to the Industrial Revolution. Completed in 1726, it holds the distinction of being the world’s oldest surviving single-arch railway bridge. Built to carry wooden wagons filled with coal from the Tanfield Colliery to the River Tyne, the arch formed part of the Tanfield Railway—the oldest existing railway in the world.

Commissioned by engineer Ralph Wood, Causey Arch spans over 100 feet across a wooded gorge and rises nearly 80 feet above the stream below. Constructed entirely from local sandstone, it was an ambitious engineering feat for its time. With no mortar or iron reinforcements used in the arch, its survival to the present day is a testament to the skill of its builders. Initially, it was thought that a double arch would be necessary for stability, but Wood insisted a single arch would suffice, and he was correct.

The bridge was used for horse-drawn coal wagons until the mid-19th century, after which it fell into disuse. Today, Causey Arch is part of a scenic woodland trail and attracts walkers, history enthusiasts, and photographers alike. Interpretive signs and nearby remnants of the industrial past—like the old wagonways and mine workings—help visitors appreciate the area’s coal mining heritage.

Causey Arch is not just a structure; it symbolizes the beginning of an era where engineering and industry would reshape Britain and the world. Its peaceful woodland setting today contrasts sharply with its once-smoky, coal-laden past. As a scheduled ancient monument, it’s protected and celebrated as a crucial piece of engineering history, reminding visitors of the North East’s vital role in powering the Industrial Revolution.
