They survive as accidental evidence of the construction process itself, the points where timber centring, the temporary wooden framework used to support the arch while the mortar set, was once braced in place. Once the arch was complete and the centring struck, the corbels became redundant, yet here they remain, readable to anyone who knows what to look for.

The bridge sits on the northern edge of the demesne of Warrens Court, a country estate in Carrigdarrery, and crosses the Buingea River by means of three segmental arches built with roughly cut voussoirs, the wedge-shaped stones that form the curve of an arch, and pointed breakwaters on the piers to deflect the current. It appears on the Ordnance Survey six-inch map of 1842, which also records what was then a small tributary running some fifteen metres to the south. That tributary has since shifted its importance: the river now flows mainly through a tall segmental arch at that southern point, while the original crossing, once the principal route over the Buingea, has been left to carry the road over much reduced water. The bridge is 5.2 metres wide and has been repaired in recent years, which has preserved its fabric without erasing the older details embedded in the stonework.
