Description

Pen-pedair-heol Bridge, also known as Canal Bridge No 110, is a single-span hump-backed bridge made of rubble sandstone. It features a segmental arch with thin voussoirs and a keystone located on the west side. On the east side, which is downstream, there is a cast iron plaque displaying the bridge number in relief. The parapets of the bridge are splayed and include a square end pier to the northeast, beyond which there is a stone stile. The copings consist mainly of upright stones, with some flat stone replacements.
