Cadw's description

About 1200m to the north of the Church of St Dennis at Llanishen but approached down a long lane from the north west beginning at Hill Farm.

A probably early C19 bridge, now a rare survival, but once characteristic of the apparently random road pattern in these remote rural areas. It gives access up to the Monmouth-Chepstow turnpike via Pant-glas Farm, but now carrries only a footpath.

The bridge is built of red sandstone conglomerate rubble with dressed voussoirs to the single segmental arch. Rounded coping stones to the parapet. The abutment walls are splayed sharply to allow waggons to make the right angled turn to the mill which may suggest that the bridge was reconstructed contemporaneously with the mill building.

Included as a rare survival of an unaltered early C19 bridge of the pre-turnpike roads on a road now declined to a footpath.
