The road, laid from flat stones roughly one to one and a half metres wide, can be traced intermittently for around seventy metres as it curves away from the lake shore towards the north-east. Bog, which is essentially waterlogged, oxygen-poor peat, is one of the better environments for preserving ancient timber, stone, and organic material, and this trackway owes its survival to precisely those conditions.

The stones themselves are granite, laid as a bed rather than a raised causeway, suggesting a practical, load-bearing surface intended to carry people or goods across ground that would otherwise have been too soft to cross with any reliability. About a hundred and eighty metres to the south-west lies a lake dwelling, the kind of settlement built on a constructed island or platform in shallow water, sometimes called a crannog, offering security to its inhabitants by placing water between them and potential threats on land. The proximity of the trackway to that dwelling is unlikely to be coincidental. Tim Robinson documented the site in 1985, and it was later included in Paul Gosling's published archaeological inventory of West Galway in 1993. The relationship between the road and the lake settlement raises the obvious question of whether this granite path formed part of the approach to the dwelling, guiding people from firmer ground to the water's edge across the softness of the bog.
