It is a togher, the Irish term for a timber trackway built across boggy or waterlogged ground, and it belongs to a classification system used to distinguish between different methods of construction and levels of engineering effort. A class 3 togher typically represents a more substantial form of these ancient roads, laid down to provide reliable passage where the ground would otherwise have made travel difficult or impossible.

Togher construction has a long history in Ireland, stretching back thousands of years, and the bogs that once made travel so treacherous have in many cases preserved these wooden structures with remarkable fidelity. The Corragarrow example was identified during a field survey, with details communicated by B. Raftery, a scholar closely associated with the study of Irish bog roads. The work of recording sites like this one was carried out by the Irish Archaeological Wetland Unit, based at University College Dublin, which systematically documented trackways and other features across Ireland's midland bogs before drainage, turf-cutting, and development could erase them from the record entirely. The orientation of the Corragarrow togher, running broadly between north-north-east and south-south-west, suggests it was laid with some deliberate purpose in mind, perhaps connecting settled areas or crossing a particularly difficult stretch of wet ground along a meaningful route.
