Set into the bases of the piers are small niches, recesses that were almost certainly used to support the temporary wooden framework, known as centering, that held the stones of each arch in place while the mortar cured. Once the arch could bear its own weight, the centering was removed, but the niches were simply left in place. They are a quiet record of medieval or early modern building practice, readable if you know what to look for.

The bridge spans the Maglin River on two semicircular arches, both of which have been repaired at some point, and measures 7.33 metres in width. On the upstream side, the masonry narrows to a blunt point, a breakwater designed to divide the current and reduce the force of water pressing against the piers during floods. Beneath the bridge, the riverbed has been paved, a detail that would have helped prevent the scouring action of the water from undermining the foundations over time. None of these features are unusual individually, but together they make the bridge a reasonably complete example of practical pre-modern engineering, modest in scale but coherent in its logic.

The paved area beneath the arches is visible from the riverbank and worth a look if the water level is low enough to allow it. The niches in the piers are easier to examine from below than from the road above, where the bridge presents an entirely ordinary face to passing traffic.
