Running roughly northwest to southeast, it carries four arches of noticeably different character: the two arches nearest the northwest bank are almost semicircular, spanning around three metres each, and built with roughly shaped voussoirs, the wedge-shaped stones that lock an arch together. The two arches on the opposite side are segmental, meaning they describe a shallower curve rather than a full half-circle, and their voussoirs are shaped and rusticated, meaning the stone faces have been deliberately worked to give a textured, projecting finish. The contrast between the two pairs suggests the bridge may have been widened or altered at some point, the older, simpler construction sitting alongside more dressed stonework.

The whole structure is built of random rubble, which in Irish vernacular building means undressed stone laid without regular coursework, bound together by the logic of the arch rather than fine masonry. Three low pointed cutwaters project from the upstream face of the piers, each about 1.15 metres wide; these are the angled projections designed to split the current and reduce pressure on the piers during high water. One small anomaly stands out: the northwesternmost arch is dry, meaning the river no longer flows beneath it. Whether this reflects a change in the river's course, seasonal variation, or the cumulative effect of alterations to the channel is unclear. The bridge has been extended on the downstream side and reinforced with concrete at the arches and riverbed, the kind of practical intervention that keeps old crossings in service but softens the original fabric. Beneath the concrete, though, stone paving is still visible on the riverbed, a quiet trace of the earlier structure surviving under the modifications.
