Five large semicircular arches span the water, their voussoirs, the wedge-shaped stones that lock an arch into place, cut and dressed from limestone with a precision that contrasts with the rougher coursed rubble making up the main body of the bridge. The width runs to around 7.7 metres, enough for a working rural road, and the whole thing carries the appearance of a mid-nineteenth-century construction, a period when improving landlords and public works schemes were reshaping the infrastructure of rural Ireland.

The engineering details speak to considered construction rather than hasty utility. On the upstream, western side, low pointed cutwaters project from the piers; these angled projections are designed to divide the current and deflect flood debris, reducing the pressure on the structure during high water. The piers themselves rest on ashlar limestone at their base, that is, finely squared and smoothed stone, providing a stable footing in the riverbed. A vertical stone coping once ran along the top of the parapet walls, though only remnants survive. To the north, three smaller overflow arches allowed excess water to pass through during flooding, a practical precaution on a river prone to seasonal rises.
