Overbridge carrying the track to Pont y Gwaith over the Penydarren tramroad, said to be mid C19 as crossing a diversion on the tramroad. The bridge immediately adjoins the bridge over the Taff Vale railway opened in 1841 and may have been rebuilt to accommodate the altered roadway. Restored as part of the Trevithick 2004 Project.


Road bridge over former tramroad, abutting railway bridge. Rubble stone, tall narrow arch with stone voussoirs and rubble stone, the parapets sloping up with roadway to abut railway bridge parapets.
