This is a togher, a form of wooden trackway built across boggy or waterlogged ground to allow passage where the land would otherwise swallow a person whole. The Corlea area is already known for one of the most remarkable examples of such engineering in Ireland, and this particular structure belongs to the same tradition, if in a far more fragmentary condition.

Classified as a class 2 togher, meaning it was constructed from longitudinal roundwood and brushwood rather than the large oak planks associated with the grander class 1 examples, this trackway was built mainly from hazel and birch. Both are fast-growing, manageable timbers, well suited to being cut and laid by communities working with the materials immediately to hand. The structure runs on an east-northeast to west-southwest orientation and survives to a depth of only around ten centimetres, a reflection of how badly damaged it has become over time. Whether that damage came from turf-cutting, the natural compression of the bog, or simple age is not recorded, but what remains is enough to identify the basic construction method and the species of wood involved.
