Its profile alone sets it apart: a pronounced arch that rises sharply above the roadway, a shape common to older Irish bridges before engineering fashions favoured flatter, more carriageable crossings. That distinctive hump was not mere aesthetics but a practical consequence of the arch form, where a steeper rise helped distribute load and resist the lateral thrust of the stonework.

The bridge carries its long axis on a northwest to southeast alignment and spans the Gweestin on three segmental arches, each formed with roughly shaped voussoirs, the wedge-cut stones that lock together at the crown of an arch to carry weight through compression rather than adhesion. The material throughout is random rubble sandstone, meaning the stones were laid without being cut to uniform courses, a technique that reflects local vernacular practice and the availability of material close to hand. On the upstream face of the piers sit two low pointed cutwaters, projections designed to divide the river current and reduce pressure on the bridge during high water or flood. The parapets are finished with vertical stone coping along their tops, a detail that adds a degree of formality to what is otherwise a plainly functional piece of rural infrastructure.
