Built 1806-8 by the engineer George Overton to replace an earlier bridge, sited immediately S of the present bridge, of a tramroad built in 1793, upon which raw materials were carried to the furnaces of Hirwaun ironworks and limestone was brought from the quarries at Penderyn.
A high single-track causeway approximately 100m in length, of snecked rubble, in parts rebuilt in coursed rubble. It crosses the Afon Cynon in a single span with segmental arch and narrow dressed-stone voussoirs. It is abutted on the R bank by coursed rubble revetments. The flat deck is a footpath retaining some stone sleeper blocks (overgrown at the time of inspection).
Listed for its industrial archaeological importance as an early example of railway engineering.
