It is a togher, a type of ancient trackway built from timber or brushwood laid across waterlogged or boggy terrain to allow passage where the ground would otherwise swallow a traveller whole. This particular example is classified as a class 3 togher, a category indicating a relatively simple form of construction, and it runs on a northeast to southwest orientation across the landscape.

The site was identified during a field survey in 1989, noted by archaeologist B. Raftery. Toghers of this kind are among the more quietly remarkable survivals in the Irish archaeological record. Bog conditions, with their low oxygen levels and acidic chemistry, can preserve organic material for centuries or even millennia, meaning that timber laid down by hands long gone can still be recovered in recognisable form. The Irish midlands in particular contain a dense concentration of such trackways, many of them only coming to light when turf cutting exposes what lies beneath the surface. Corragarrow's togher, with its northeast to southwest alignment, may once have connected patches of dry ground, guided people or animals across an otherwise impassable stretch, or linked settlements whose names and locations are now unknown.
