Cadw's description

The bridge carries the road to Plas-y-Bryn over the Afon Gwyrfai some 400m E of the A487, SE of the centre of Bontnewydd.

Later C19 road bridge over Afon Gwyrfai carrying minor road to Plas-y-Bryn. Very similar to railway bridge W of Bontnewydd.

Rubble stone with red brick arches. Two broad segmental arches, with 4 courses of brick to arch-rings, raised high on centre pier and side abutments. Rubble stone flat parapets.

A dramatic masonry bridge, the scale reminiscent of railway structures.
