Cadw's description

On a track immediately to the west of the A 4085 at Coed Plas-y-nant spanning a series of small but spectacular waterfalls on the Afon Gwyrfai.

Shown on the 1839 Tithe Map, the bridge was constructed to cross the rapid and fast-flowing waterfalls of the Afon Gwyrfai at this point.

Bridge. Roughly coursed rubblestone with stone-on-edge coping. Wide single-span elliptical arch with voussoirs and arch-ring.

Included as a simple and unaltered early C19 bridge of vernacular type in a picturesque location.
