Description
The building is a single arch bridge, slightly humped in profile, spanning the Sirhowy River. It is constructed of narrow, regularly-laid rubble stone with deeply dressed stone voussoirs featuring a prominent keystone. Only one original flat coping stone remains at the north-east end, with the remainder having been replaced with concrete. The bridge approaches are splayed and have been repaired, and there is an offset in the north-east abutment. The highest point of the bridge is not centred directly above the river arch.
