It is a togher, the Irish term for a raised timber roadway built across boggy or waterlogged ground, and at just 1.1 metres wide it was never intended for carts or livestock drives. This was a path for people on foot, picking their way across ground that would otherwise have been impassable.

The structure is classified as a class 3 togher, meaning it consists of a single layer of brushwood with occasional roundwood timbers interspersed throughout. That combination was a practical solution: the brushwood spreads the load across soft ground, while the heavier roundwood pieces add stability underfoot. The technique required no great engineering, only a reliable knowledge of local materials and the terrain. Peat bogs are remarkable preservers of organic material, and it is because of the acidic, oxygen-poor conditions of the Longford bogland that this modest construction has survived at all, its wood still largely intact long after the community that built and used it has vanished entirely from the record.
