Description
The Taff Vale Railway bridge over Cwm Clydach is a wide, triple-arched railway bridge built to slightly skewed specifications. It crosses the main road that runs north to south along the west bank of the River Taff, located at the center of Nant Clydach, which flows into the Taff a short distance to the east. To the north, there is a lane along the north side of Nant Clydach.
Constructed from coursed rock-faced stone, the bridge features very deep rock-faced voussoirs, some of which have diamond-shaped ends, each adjoining a separate stone course. The voussoirs are tooled as quoins on the return inside the arch. The bridge has a deep and wide plinth, and the arches are uneven, with the river arch being the widest. There are some curved rubble abutments at the banks. The low parapet is made of tooled stone and is topped with iron railings and three rows of wire.
Under all three arches, there is a noticeable break between the east and west sides, likely indicating the track-doubling, although there is no change in masonry style.
