Merthyr Tydfil
Pont y Cafnau 2025
Located just below the confluence of the Afon Taf Fawr and the Afon Taf Fechan rivers, it is now used as a public footpath. This cast iron aqueduct (1793), known as the ‘bridge of troughs’, was an early prototype and is a unique survivor, and has been acknowledged as the world’s oldest surviving iron railway bridge. It was built by the chief engineer of Cyfartha Ironworks to carry the works’ tram-line and its water supply over the River Taff. The bridge is a Scheduled Ancient Monument and Grade II Listed structure.
