The voussoirs, the wedge-shaped stones that form each arch, are roughly cut rather than finely dressed, giving the whole structure a workmanlike solidity rather than any pretension to elegance. On the upstream face, low pointed breakwaters project from the piers, a practical feature designed to split the current and reduce the pressure of water and debris against the stonework during high flows.

Bridges of this type, multi-arched and hump-backed with pointed cutwaters, are broadly characteristic of Irish road bridge construction from the seventeenth through to the early nineteenth centuries, though this particular crossing over the Knoppoge has not been assigned a precise date in available records. The five-arch arrangement suggests a river prone to swelling considerably after rain, requiring the load to be distributed across multiple openings rather than concentrated in one or two wider spans. The rough finish of the voussoirs indicates a builder working with locally sourced stone, shaped on site to the tolerances needed for a functional arch rather than a polished civic monument.
