It is a togher, the Irish term for a road or causeway built through boggy or marshy terrain, and this particular example belongs to what archaeologists classify as a class 3 type, a category that covers relatively simple constructions, typically involving brushwood, branches, or light timber laid directly onto the bog surface to provide a firm enough path for people and perhaps livestock.

The trackway was noted during a field survey in 1988 and recorded in Barry Raftery's 1990 study of Irish bog roads. Toghers of this kind are significant not only as feats of practical engineering but as evidence of organised movement across a landscape that modern observers might assume was simply impassable. Ireland's raised bogs preserve organic material with unusual fidelity, which is why wooden trackways that might otherwise have rotted away centuries ago can survive for millennia in the anaerobic, acidic conditions below the surface. The northeast to southwest orientation of the Annaghbeg togher suggests it was aligned with some purposeful route across the wetland, though precisely where it was leading, and when it was built, is not detailed in what has been recorded about it.
