Summary :
The ruined bridge over the Afon Machno known as "Roman Bridge" consists of a single span of 8.2 metres. It no longer has parapets, and the carriageway masonry was removed: now there is only a turfed route across the bridge.

The age of the bridge is uncertain. It is considered to be of 16th- or 17th-century date, and is almost certainly the predecessor of the 19th-century Pont y Pandy. It is possible that it may be Pontrhydgynon, a bridge referred to in the 1662 general sessions report as "ancient".

Description :
