Cadw's description

Located below Ynys Pandy mill, carrying the road to Cwmystradllyn over the Afon Henwy.

A simple country bridge built in the late C18 or early C19 perhaps in connection with the early development of slate extraction at Gorseddau. On the NE side, the ruins of the weigh-house serving Ynys Pandy felin llechi.

Built of local rubble slate stone. A segmental arch rising 2.1m and spanning 5.4m composed of stone voussoirs with flush spandrels and parapets, coped with stone-on-edge copings. The carriageway over is 3.1m wide between the 45cm parapets.

Included as a modest country bridge of group value with Ynys Pandy mill.
