Alongside its single arch spanning the river itself, the bridge includes two additional dry arches built into the floodplain to the west, stone openings that carry no water in ordinary conditions but exist to allow floodwater through when the river rises and spreads across the lower ground. It is a practical piece of engineering, and an honest one.

The bridge is built of random rubble, the loose, uncoursed stonework typical of older rural construction where locally gathered stone was laid without the regularity of dressed masonry. Its arches are segmental, meaning they describe a shallow curve rather than a full semicircle, and the voussoirs, the wedge-shaped stones that lock an arch together, are described as roughly shaped, suggesting a working bridge rather than a prestige one. Two pointed cutwaters project from the upstream face of the piers on the north side, rising to the full height of the arches. Cutwaters are the angled projections built to split the current and reduce the pressure of water against the piers, and the pointed form here is well suited to a river that can push hard in flood conditions. The original width of the bridge was 5.8 metres, running east to west, though an extension has since been added on the downstream side, giving the structure a slightly asymmetrical profile when viewed from the bank.
