Walnut Tree Viaduct

The Walnut Tree Viaduct was a railway bridge spanning a valley with seven iron girders supported by tall brick columns. The structure was built using millions of bricks and represented an ambitious engineering project of the early 1900s.

This railway bridge was built in 1901 by the Barry Railway Company and connected coal mining regions to the coast. It remained in service as a key transport link in South Wales until closure in 1967.

The viaduct represented the industrial advancement of South Wales, connecting multiple railway systems and transforming the region's transportation capabilities during the coal mining era.

Today only fragments of this former bridge remain standing in the landscape. You can see the surviving brick columns most clearly when traveling along the nearby main road.

Two brick columns still stand in the landscape along with remnants of the tunnel that once connected to this bridge. These surviving elements offer a glimpse of how the railway infrastructure dominated this valley during the coal transport era.
