Its two segmental arches, the curved spans formed from wedge-shaped stones known as voussoirs, are not a matched pair. The south-western arch sits lower and carries a narrower span than its north-eastern counterpart, giving the bridge an asymmetry that suggests either a phased construction or an adaptation to the particular behaviour of the river at this crossing point. The voussoirs themselves are punch dressed, meaning their faces were worked with a pointed tool to produce a rough but deliberate texture, yet they vary noticeably in size and shape, which points away from any pretension to formal engineering and towards the practical traditions of local stonework.

The bridge is built from random rubble, the term for walling in which stones are laid without any attempt at regular coursing, and it spans the river along a north-east to south-west axis, measuring 6.3 metres in width. Somewhere along the way, the upstream parapet was replaced in concrete, and concrete coping was added to the downstream parapet as well. These repairs are common enough on rural bridges that continued to carry traffic long after their original construction, and they tend to obscure the original profile without entirely erasing the character of the older structure beneath. The unmatched arches remain the most telling feature, quietly recording whatever decisions, constraints, or compromises shaped the bridge when it was first put across the river.
