Built probably in the mid C19 to provide a level crossing of the river at this point.


Built of coursed squared rubble, with a single large semi-circular arch of flush even shale voussoirs springing from native rock and rising to a keystone. Flush spandrels and projecting string course, and a parapet of flat coping stones. The abutments are slightly battered and end in demi-piers. The arch spans approximately 10.7m, rising 6.2m above the river, and carries a carriageway 5.5m wide with 53cm parapets.

Reasons for Listing

Included as a robust and characterful C19 road bridge, one of a series of such bridges carrying the main road over small deep valleys of tributaries of the Afon Dugoed.
