Iron Bridge over River Rhymney

Single-carriageway 2-span cast iron bridge. Four central T-section piers carry segmental arches supporting the deck. The central spandrels have circles, while in the outer spandrels are half circles (similar to the Iron Bridge in Shropshire). One arch on the downstream side bears the date 1829 in relief. One arch on the upstream side is partly missing. The abutments are of coursed stone and are splayed outwards. The deck is laid with cast iron plates (now grass covered) and a has a parapet of cast iron railings with spear finials. Above the abutments the parapets continue as white-brick walls curving outwards and terminating in round piers (now mostly collapsed). In the L bank the abutment has an arched culvert, with arch ring on the downstream side and collapsed on the upstream side.
