What earns it a closer look is its construction: four segmental arches, meaning arches that form only a shallow curve rather than a full semicircle, built from rough stone voussoirs, the wedge-shaped blocks that lock an arch together under their own compression. The bridge measures just over seven metres in width, and on its upstream face it carries low pointed breakwaters, narrow projections of masonry designed to split the current and deflect debris before it can press against the arch faces.

The breakwaters are a small but telling detail. On older Irish road bridges they are a practical response to rivers that carry heavy loads of silt, branches, and flood material, particularly on upland or semi-upland watercourses like those running through mid-Cork. The pointed profile, rather than a rounded one, is the more efficient shape for shedding fast-moving water, and its presence here suggests the builders had a clear understanding of the river's behaviour. The rough dressing of the voussoirs, rather than ashlar or cut stone, is typical of rural bridge construction where local material was used economically and speed of construction mattered as much as finish.
