Causey Arch

About

The Causey Arch is a bridge near Stanley in County Durham, northern England. It is the oldest surviving single-arch railway bridge in the world, and a key element of the industrial heritage of England. It carried an early wagonway (horse-drawn carts on wooden rails) to transport coal. The line was later diverted, and no longer uses the bridge.
