It is classified as a class 2 togher, the term used in Irish archaeology for a trackway constructed across soft or marshy ground, typically built from split or round timber planks laid transversely across longitudinal runners. Class 2 toghers represent a more substantial form of construction than the simplest brushwood pathways, suggesting a route that saw regular or purposeful use rather than occasional crossing.

Bog roads of this type have been found across Ireland, and they tend to date anywhere from the Bronze Age through to the early medieval period, though without excavation data it is difficult to assign a precise date to any individual example. What makes them consistently remarkable is the reason they survive at all: the anaerobic, acidic conditions of raised bogland effectively halt decay, preserving timber that would otherwise have rotted away millennia ago. The Kilcrin togher belongs to a wider tradition of engineered movement across the Irish midlands and west, where expanses of bog were not simply obstacles but managed landscapes, crossed by maintained routes that connected communities, farms, and territories.
