Built from birch roundwood and brushwood laid across wet ground, it is what archaeologists call a togher, a timber trackway constructed to allow movement through boggy or waterlogged terrain that would otherwise have been impassable. This particular example was graded as class 3, meaning it was among the less elaborate of its kind, assembled without great care or precision but functional enough for whoever needed to cross.

The trackway runs on an east-west orientation and measures roughly 1.9 metres wide and 0.4 metres deep. It was laid using longitudinal roundwood timbers, each averaging about 6.5 centimetres in diameter, supplemented with thinner brushwood averaging around 1.5 centimetres across, both materials drawn from birch. The choice of birch is unsurprising given how commonly that tree grew in the margins of Irish bogland, but the overall construction was considered poor, suggesting this was a practical, perhaps temporary, solution to a recurring problem of movement across difficult ground rather than a planned piece of engineering. Toghers of this kind appear throughout the Irish midlands, preserved by the same waterlogged, oxygen-poor conditions that make bogs so destructive to ordinary timber above ground.
