This afternoon I visited Causey Arch in County Durham with my dad. The Arch is the oldest surviving single-arch railway bridge in the world. It opened for service in 1726, and carried on a wooden railed tramway, around 900 wagons per day over the Causey Burn. The tramway literally "Teckin' Coals to Newcastle." Nearby is the Tanfield Heritage Railway, once part of the network of tramways that serviced the local collieries in this area.
We approached the Arch along the valley floor, following a woodland path along the banks of the Causey Burn before walking up to the arch and crossing the bridge on a circular walk. Hope you can appreciate the scenery and its grandeur as much a we did.
