Description

Pont Maesmochnant is a bridge constructed in local uncoursed quasi-rubble masonry, featuring a single segmental stone arch that spans approximately 10 meters. The carriageway measures about 6 meters in width and is flanked by parapets that rise to about 1 meter in height. The parapets are slightly angled outward at each of the four ends and finish with square block copings. In the center of the coping on each side, there are sections with weathered and slightly overhanging copings, while the rest of the bridge is notably devoid of decorative features.
