It is a togher, a type of timber trackway laid across boggy or waterlogged terrain to allow passage where the ground would otherwise be impassable, and this one was entirely unknown to the archaeological record until aerial photography revealed its outline in 1996.

What the aerial images showed was a road that does not meander or detour. It travels in a direct line across the bog, linking Cullahill to the northeast with Dromard More to the southwest, and it appears to have been positioned deliberately at the narrowest crossing point between the two. That practical logic, choosing the shortest distance across unstable ground, is characteristic of togher construction, where every additional metre of timber laid down represented significant labour. The site was formally recorded as part of the Archaeological Inventory of County Tipperary, compiled by Jean Farrelly and Caimin O'Brien and published in 2002, but the discovery itself belongs to that now-familiar pattern of aerial survey revealing what centuries of peat accumulation had quietly buried and preserved.
