It is the kind of structure that raises more questions than it answers, not least because the southern approach shows no trace of a causeway, which leaves you wondering how anyone was meant to reach it in the first place.

The bridge appears on the 1916 Ordnance Survey six-inch map under the name Athmore, with stepping stones also marked at the same location, suggesting the crossing existed in some form before the bridge was built, or that both solutions coexisted for a time. What survives today are remnants of the piers on the north and south banks. The southern pier, measuring up to 2.9 metres long and 1.45 metres high, is drystone construction, meaning it was built without mortar, with faced surfaces that show some care in the laying but no particularly distinctive dressing or tooling. To the north, a moss-covered drystone wall is still visible. The structure was formally noted as a potential site in the 1992 Sites and Monuments Record and again in the 1996 Record of Monuments and Places, categories that flag a location where the name or evidence suggests something of historical significance without enough surviving fabric to confirm it fully. The name Athmore itself, from the Irish áth mór meaning great ford, points to a crossing of some local importance, possibly predating the bridge by a considerable stretch.
