It is a togher, a type of wooden roadway laid across boggy or waterlogged terrain to allow passage where the ground would otherwise be impassable, and this particular example is classed as a class 3 togher, a category that typically refers to a relatively simple form of construction, often comprising brushwood, planks, or split timbers laid directly onto the bog surface.

The structure was noted during a field survey in 1988, with its east-west orientation recorded in a personal communication from B. Raftery, one of the foremost scholars of Irish bog roads and prehistoric trackways. Togliers of this kind are among the more quietly remarkable survivals in the Irish archaeological record. Bogs preserve organic material with unusual fidelity, and wooden trackways that might have rotted away in any other landscape can endure for thousands of years beneath the peat. Without that preserving quality, the everyday infrastructure of early Irish life, the paths people used to cross difficult ground, to reach grazing land or neighbouring settlements, would be almost entirely invisible to us.
