One spans a deep rocky gorge, the other sits dry above a level platform, and the stonework of each reflects that difference in a way that rewards a closer look.

The structure runs on a northwest to southeast axis and is built of random rubble sandstone, the kind of construction common to older Irish bridges where dressed stone was expensive and local material was shaped to fit as needed. The southeast arch, positioned over the gorge where the river runs, is semicircular, the older and more conservative form, and is formed with narrow, roughly shaped voussoirs, the wedge-cut stones that lock an arch into tension. The northwest arch is segmental, meaning it describes a shallower curve than a full semicircle, a form that became more common as builders grew confident in calculating lateral thrust. Some of its voussoirs are rusticated, meaning their faces are left deliberately rough or boldly cut to give a texture that plain ashlar lacks. The pier between the two arches shows rusticated ashlar on its exposed northwest face, dressed stonework where it meets the eye, even if the bulk of the bridge is rubble. The parapets are finished with vertical stone coping along their tops.
