It runs for roughly 260 metres in a north-west to south-east direction before bending northward towards the Nuenna river, and it passes within thirty metres of a ringfort. What makes it quietly remarkable is not any single feature but the fact that it still connects, at least in memory and in faint topographical trace, a whole constellation of medieval sites that once formed a coherent local landscape.

The road's significance was noted by William Carrigan in his 1905 history of the diocese of Ossory. He recorded that it linked the churches and castles of Killashoolan with those of Ballylarkin, passing by way of Kilrush castle and crossing the Nuenna by a bridge that was already almost entirely destroyed by his time. Carrigan also noted a field in Ballylarkin called the "Thur-duv," where a feature known as the "monument bush" stood along the road's line. The name Thur-duv likely reflects an Irish place-name element, and the monument bush suggests the kind of local landmark, probably a lone tree or shrub at a significant boundary or grave site, that rural communities preserved in field names long after the original meaning had faded. The road itself would have served the practical needs of a medieval parish, connecting ecclesiastical and defensive centres across what is now quiet agricultural land.
