Description

The bridge over Cwm Hafod is a Grade II listed structure featuring a deep curved revetment made of coursed rubble, built against the hillside to support the road across the steep Cwm. It has parapets topped with saddle back coping and includes a distinctive pointed arched culvert for the stream, which is constructed with rubble voussoirs.
