Taff Vale Railway bridge over Cwm Clydach
Unitary Authority
Rhondda Cynon Taff
Location
On the very S boundary of the community, at the junction of Cwm Clydach with Taff Vale.
History
The Taff Vale Railway was the original and leading independent railway of the region in mid C19, opening up access between the iron and coal-producing Valleys and Cardiff, with its main outlet on Bute West Dock. The congestion on the Glamorganshire Canal of the 1830s was the stimulus and its promoters were ironmasters Sir John Josiah Guest head of Dowlais Ironworks and Walter Coffin who developed coal-mining in the Rhondda. It was engineered by Isambard Kingdom Brunel and received Royal Assent in 1836. Cardiff to Navigation House at Abercynon section was opened in 1840, onward to Merthyr in 1841. At first a single track, the doubling to Navigation House was achieved in 1847. The original line is 24.5 miles (39.4 km) long; it subsequently developed a number of branches. The route in this area follows the left bank of the River Taff, here crossing Cwm Clydach. The bridge has been reinforced in 1980s and 90s with iron ties on patras plates.
Exterior
A wide triple-arched slightly skewed railway bridge crossing at S the main road which runs N/S along the W bank of the River Taff, at centre Nant Clydach which flows into the Taff a short distance to E, and at N a lane along the N side of Nant Clydach. Built of coursed rock-faced stone with very deep rock-faced voussoirs, some with diamond-shaped ends, each adjoining a separate stone course; the voussoirs are tooled as quoins on the return inside the arch. Deep and wide plinth. Uneven arches, the river-arch the widest. Some curved rubble abutments to banks. Low parapet of tooled stone with iron railings and 3 rows of wire.
Interior
Under all three arches there is a noticeable break between the E and W sides, no doubt representing the track-doubling, though there is no change in masonry style.
Reason for designation
Listed as a fine tri-partite bridge of the historically pioneering Taff Vale Railway. Group value with nearby road bridge.
