Carrying a road across the River Blackwater at the line where County Cork meets County Kerry, it is a humped-back structure oriented east to west, wide enough at 5.2 metres for the traffic of its era but narrow by modern standards. What makes it slightly irregular is the arrangement of its arches: three are segmental and nearly semicircular, each spanning around 4.3 metres, while a fourth, lower segmental arch sits on the western side, as though the crossing was adjusted to suit the river's behaviour at that bank. The whole thing has been heavily repaired with cement at some point, which softens the original stonework but does not entirely obscure the character beneath.

The bridge carries the appearance of an eighteenth or early nineteenth-century construction, a period when improving landlords and county grand juries across Munster were investing in road infrastructure to open up agricultural hinterlands. The voussoirs, the wedge-shaped stones forming each arch, are described as rough rather than finely dressed, suggesting solid utility rather than civic display. The most carefully worked element is the pointed cutwaters on the upstream face, built from ashlar limestone. Cutwaters are the projecting piers that divide the current and deflect debris before it can build pressure against the arches; pointing them sharpens that function and, in better-quality bridges, also signals a degree of craft in the design. Here the ashlar limestone cutwaters sit in some contrast to the rougher stonework elsewhere, hinting at a builder who knew where precision mattered most.
