Cadw's description

Roadbridge to a minor country road, spanning the Afon Deunant c2.5kms S of Bryn Rhydarian and c2.5kms ESE of Llansannan.

Late C18 roadbridge, built in 1785, the bond of November 1784 specifying that the bridge be built by 24th June of the following year. The contract was awarded to David Lewis, mason, and the bridge was constructed from stone quarried from the Nantglyn Quarry. David Lewis was also the mason who worked on Pont Brynrhydarian and may also have worked on other similarly detailed bridges in the area.

Roadbridge, built of local rubble masonry; a single wide segmental span over the river, the stonework of the arch slightly recessed from the main wall of the bridge. The walls of the bridge curve outwards at the extreme ends and the walls of the parapets stand to a height of c1m above road level, with plain copings.

Included as a good example of a late C18 roadbridge.
