At just over five metres wide and with a single semicircular arch spanning two metres, it is a modest structure by any measure, yet it carries a road that was deliberately engineered in the mid-eighteenth century to link Killarney with Castleisland. The overgrowth that has crept across it gives the impression of something long forgotten, though the road it serves has not entirely been abandoned.

The bridge is built in random rubble, meaning the stones were laid without being cut to uniform shapes or courses, a common and economical approach in rural Irish construction of the period. The arch itself is formed with voussoirs, the wedge-shaped stones arranged in a curve that distribute the weight of the structure down through the piers, though here they are described as roughly shaped rather than finely dressed. The parapets, the low walls along each side, have been given concrete coping at some point, a later practical addition to keep water from working into the stonework. The Killarney to Castleisland road of which this bridge forms a small part was one of many such routes developed across Munster during the mid-1700s, a period when improving inland roads was seen as essential to connecting market towns and facilitating movement across difficult terrain.
