Its ten semi-circular arches rise in a gentle gradation, each one slightly taller than the last as they step towards the centre of the span, giving the whole structure a quiet rhythmic quality that rewards a closer look.

The bridge is built with coarse voussoirs, the wedge-shaped stones that lock an arch in place, and features tall pointed breakwaters, the projecting piers designed to divide the current and deflect debris carried downstream. These are hallmarks of traditional Irish masonry bridge construction, practical in origin but visually distinctive. The original carriageway was roughly four metres wide, a measurement that tells you something about the traffic it was built to carry. At some later point the bridge was widened by approximately three metres on its downstream, eastern side, a common intervention on older bridges as road use intensified, and one that often leaves a visible seam or change in stonework where old and new construction meet.
