Pont-y-Bryn including walls and parapets to carriageway adjoining to the E and W

Pont-y-Bryn is a five-span road bridge built as part of a raised carriageway that connects to the main Dee bridge, the Pont Fawr, located about 60 meters to the east. The bridge is constructed from rubble and raises approximately 2.5 meters above the flood plain, featuring rubble parapets that average 0.80 meters in height, topped with slate-stone slab copings. The bridge itself is about 25 meters long and has five segmental arches, which are made with rough-dressed voussoirs set below narrow stone archrings. The primary (southern) section includes low triangular cutwaters and flat buttresses on top. The north side also has similar flat dividing buttresses.

To the west of the bridge, the carriageway has a rebuilt parapet on the north side, although the original slab copings have been reused. Immediately to the west of the bridge is a four-span flood arch arrangement with flat slate-stone lintels, which was built at the same time as the raised carriageway. To the east of the bridge, the parapet walls extend for about 30 meters on either side. On the north side, just east of the bridge, there is a modern replacement section with a large platform buttress facing the river, which was constructed between 1983 and 1984.
