Description
Pont Eyarth is a bridge featuring a single large segmental arch constructed from hammer-dressed local limestone masonry. The common stonework of the bridge is set slightly forward of the faces of the voussoirs, and there is a slight string course at the base of the parapet. Each end of the span has a slight turn-out to a buttress, and the corners are protected from traffic damage on the inside by stone bollards. The carriageway gently rises from each side to a slight central hump and measures about 3½ metres wide between the parapets. The land approaches at both ends are faced in similar masonry but are somewhat wider. The bridge parapets are massive and feature triangular copings.
