Cadw's description

Spanning the Afon Wnion; approximately 1km N of Brithdir. At the northern end is the T-junction with the A 494.

Wide single-span bridge probably of late C18 date; repairs to the parapets are recorded in 1828 and the bridge has almost doubled in width on the upstream side since then. Also formerly known as Pont Dolgamedd.

Rubble construction; single segmental arch with voussoirs and modern steel braces; cement-rendered soffit. Heavily-eroded inscription plaque to upstream side. Rubble abutment on downtream side at N end. Ramped roadway, built up atthe N end approaching the road junction where the 1m high parapets have been partly rebuilt; part concrete coping. On the downstream side the parapet continues along the roadside for approximately 30m beyond that of the upstream side.
