It was not rediscovered through any deliberate archaeological investigation but because a ring road needed to go through the same ground. That the Bronze Age trackway survived at all is partly down to the wet conditions that preserved it; organic materials that would rot away in drier soils were held intact in the hollow where the road's first phase was laid.

Excavated ahead of Phase II of the Southern Limerick Ring Road by Taylor in 2004, the trackway sits at the western end of a glacial ridge, about 750 metres east of the River Shannon. It appears to have been built in two stages. First, brushwood, including worked timber and animal bone as well as antler, was laid down loosely in a waterlogged hollow measuring roughly 6.5 metres by 2.5 metres. Dendrochronology, the science of dating timber by its tree rings, gave a felling date for one of the larger pieces of wood of 1577, plus or minus nine years, BC. Above the brushwood, peat accumulated naturally, and then a rough surface of small stones, none larger than about 15 centimetres, was laid across it to create a more usable path, extending to around 8.4 metres in length and 3.1 metres wide. A second, better-defined section of stone surface was recorded 7.2 metres to the south-west. Running parallel to the trackway was a line of contemporary timber posts, suggesting the route was both marked and maintained. At its north-eastern end, the trackway led toward two Bronze Age round buildings, and two fulacht fia, which are burnt mound sites associated with outdoor cooking or heating water, were located just two and twenty metres away respectively. The whole complex led ultimately to a stream.

The site itself is no longer visible; road construction proceeded after the excavation was completed, and the trackway now lies beneath or alongside modern infrastructure on the outskirts of Limerick city. Its interest lies less in what can be seen today and more in what the excavation revealed: a small, purposeful piece of Bronze Age engineering connecting domestic buildings, cooking sites, and a watercourse across difficult, boggy ground, preserved almost by accident until the twenty-first century.
