This particular example is what archaeologists classify as a class 3 togher, a togher being the Irish term for a wooden trackway laid across bog or marsh. The structure runs roughly northwest to southeast, measures about 1.5 metres wide, and survives to a depth of just under 10 centimetres, composed of seven or eight transverse roundwoods, essentially small-diameter logs laid side by side across the line of travel to form a crude but functional surface.

Corlea is already known to specialists as one of the most significant bogland sites in Ireland. The wider Corlea Trackway, a separate and more celebrated Iron Age road nearby, was dendrochronologically dated to 148 BC and used massive oak planks of considerable engineering ambition. This smaller togher belongs to a different order of construction entirely. Where the great plank roads of the Irish bogs suggest organised communal labour and long-distance movement, a class 3 togher of this kind is a more intimate thing: roundwood rather than split timber, closely spaced rather than formally jointed, the kind of crossing that might have served a local need across a few metres of difficult ground. The data underlying the record was gathered by the former Irish Archaeological Wetland Unit at University College Dublin, a body responsible for systematically cataloguing the extraordinary density of wooden trackways concealed beneath Irish peatlands before development and drainage could erase them.
