It is not made of stone or gravel but of hazel brushwood, woven into a hurdle panel and pressed into the wet ground, a construction technique used across prehistoric Ireland to create passable routes through otherwise impassable boggy terrain. These structures are known as toghers, from the Irish tóchar, meaning a causeway or road across a marsh, and they appear throughout the Irish midlands wherever the landscape made overland movement difficult.

This particular togher was recorded in 1988 and measures just under three metres in length, roughly forty centimetres wide and five centimetres deep, oriented on a northwest to southeast axis. A single stake was driven through the northeast corner to hold the panel in place. Small in scale, the structure is precise enough in its construction to suggest familiarity with the technique rather than improvisation. Radiocarbon dating placed its origin between 1209 and 926 BC, placing it firmly in the Late Bronze Age. That date range means this strip of woven hazel was laid down by someone navigating a bog during a period when metalworking was transforming Irish society and the great timber trackways of the Irish midlands, some of them far larger and more elaborate, were being laid across the landscape in considerable numbers.
