It is a togher, a type of ancient trackway built from timber to allow passage across the soft, waterlogged ground of Irish raised bogs, and this particular example is classified as class 3, meaning it was constructed using a relatively simple technique of laid timbers rather than the more elaborate planked or mortised methods found at grander sites. The bog, in its characteristic way, has preserved it.

The trackway was noted during a field survey in 1989, running east to west across the bog. The observation came by way of the archaeologist B. Raftery, one of Ireland's foremost authorities on bog roads, whose work helped bring systematic attention to these easily overlooked structures. Toghers were built across many centuries, some dating back to the Bronze Age and others to the early medieval period, and they tend to survive precisely because the anaerobic, acidic conditions of a raised bog suppress the decay that would otherwise consume wood over time. A class 3 togher typically consists of roundwood or split timbers laid transversely across the soft ground, creating a firm surface just sufficient to carry a person, an animal, or perhaps a loaded cart between otherwise impassable stretches of wetland. In a landscape where bog could isolate one settlement from another, such roads were genuinely practical infrastructure, not ceremonial or symbolic in the way that some of the more elaborate Iron Age examples appear to be.
