The bridge spans the Tralee to Killarney railway, and its construction in ashlar, that is, precisely cut and squared stone blocks, speaks to a level of craft that goes well beyond what a purely utilitarian crossing might have demanded. The elliptical arch beneath it is formed with ashlar voussoirs, the wedge-shaped stones that lock an arch into shape, and a string course, a narrow horizontal band of masonry, runs along the base of the parapet walls on either side. The overall effect is of something built to last, and to look right while doing so.

The Tralee to Killarney railway line was part of the broader expansion of Ireland's rail network through the nineteenth century, connecting two of Kerry's principal towns and opening up movement through a county where road travel had long been difficult. Bridges like this one were a necessary part of that expansion, allowing landowners whose fields the line cut through to continue moving livestock and vehicles across what would otherwise have become a permanent barrier. The use of ashlar rather than rubble stone at such a crossing suggests either local pride in the work or a contractor who held consistent standards across the line's infrastructure. The string course detail is a small but telling touch, the kind of finish that belongs to a tradition of masonry where even minor elements were expected to cohere.
