It is a togher, an ancient form of trackway constructed from timber laid across waterlogged or marshy ground to allow passage where the earth alone would not hold a person's weight. This particular example stretches thirty-five metres in length, three metres wide, and survives to a depth of around thirty-five centimetres, oriented roughly east-north-east to west-south-west across the bog.

The construction method reveals a careful, layered approach to a practical problem. The builders worked with what the local environment provided: small and large brushwood, roundwood timbers ranging from roughly six to nine centimetres in diameter, and bundles of twigs, laid predominantly in the direction of travel but with some elements placed transversely to give the surface stability. This combination of longitudinal and cross-laid material is characteristic of a class 2 togher, a designation that reflects the relative complexity of the structure compared to simpler single-layer brushwood tracks. Toghers of this kind are found across the Irish midlands, where extensive raised bogs once made movement between settlements a genuine seasonal challenge. The bog itself acted as a preservative, sealing the organic timber away from the oxygen that would otherwise have rotted it, which is why such structures can survive for centuries or even millennia beneath the peat.
