It is called a togher, the Irish term for a trackway laid across wet or marshy ground, and this particular example is modest almost to the point of invisibility: less than a metre wide and barely a hand's breadth in depth, built from interwoven brushwood and small roundwood poles of oak and ash.

The construction is classified as a class 3 togher, meaning it was made from longitudinal timbers laid end to end rather than the more elaborate transverse-plank arrangements seen in higher-classification examples. The individual poles averaged around four and a half centimetres in diameter, the kind of material readily cut from managed woodland or cleared scrub. The trackway runs east to west, suggesting it was laid with some purposeful orientation across the landscape, perhaps connecting two patches of firmer ground across an otherwise impassable stretch of fen or raised bog. Oak and ash were the timbers of choice throughout prehistoric and early medieval Ireland, both durable enough to serve underfoot and widely available. The Irish boglands have yielded hundreds of such structures, ranging from simple hurdle paths to substantial engineered roads, and they remain among the most direct evidence we have of how people moved through a landscape that was far wetter and more wooded than it appears today.
