That date places the bridge within a period of considerable road and bridge construction across Ireland, much of it driven by public works programmes in the years surrounding Catholic Emancipation and the early stirrings of famine relief infrastructure.

The bridge itself is a carefully considered piece of early nineteenth-century engineering. It spans the Brown Flesk River on a southwest to northeast axis, measuring 7.5 metres wide with three segmental arches, each roughly nine metres in span. Segmental arches, which describe a curve shallower than a full semicircle, were a practical choice for river crossings, allowing a lower profile that reduces the rise a road must climb. The main structure is ashlar limestone, meaning the stone was cut and dressed into regular blocks, while the parapets are built in random rubble, a contrast in finish that was common where the visible, load-bearing fabric of a bridge demanded precision but the upper walls did not. The voussoirs, the wedge-shaped stones that lock each arch together, are also cut and dressed limestone. Low rounded cutwaters project from both sides of each pier; these blunt the force of the current and help prevent scouring around the foundations. A string course, a narrow projecting band of stone, runs across both faces of the bridge just above the arches, and the parapet ends splay outward to finish in square terminal piers, giving the structure a composed, slightly formal appearance at its approaches.

The plaque on the northwest parapet is the detail worth pausing for. It sits on the inner face, away from the road, which may explain why the bridge tends to be passed rather than examined. Visitors approaching from the riverbank or looking back from below the arches will get the clearest sense of the cutwater profiles and the overhang of the vertical stone coping along the parapet faces.
