Description
Pont Rhydyronnen is a single-carriageway bridge with three spans, constructed from rubble stone and ramped towards the center. It features slightly recessed segmental arches made of cut voussoirs. On the upstream side, there are V-shaped cutwaters, with part of the left side rebuilt in concrete. The parapet has a cement coping that has been replaced.
