History

Disused railway viaduct on the loop that carried the 'top line' to Blaenavon from Pontnewynydd Junction. Built c1870 probably by the Monmouthshire Railway and Canal Company. Just to the SE was the Branches Fork Junction where one line went W to the Cwm-ffrwdoer collieries of Plas-y-coed, Gellydeg and Tirpentwys and another went NW under the viaduct to serve the Cwm Du pits. The viaduct now carries a cycle path.
