On their own, the fragments seem unremarkable: a length of poorly milled roundwood here, a few pieces of brushwood there. But together they preserve the faint outline of a togher, a timber trackway of the kind once laid across boggy or waterlogged ground to allow people, animals, and perhaps goods to pass through landscapes that would otherwise have been impassable.

Toghers vary enormously in their construction, from elaborate plank roads supported on driven piles to far simpler arrangements of brushwood and small timber laid directly onto soft ground. This one belongs to the more modest end of the scale. When recorded by Dunne in 1999, two distinct exposures were identified, designated 8A and 8B. The first consisted of a single roundwood timber about 1.1 metres long, oriented northwest to southeast, with two pieces of brushwood positioned nearby on a slightly different axis. The second exposure contained three degraded longitudinal elements, again oriented northwest to southeast, comprising one roundwood and two brushwood pieces of differing diameters. None of the timber showed any clear signs of deliberate shaping or tooling, which is itself informative: the simplest toghers were often built opportunistically, using whatever material was close to hand, without the kind of careful preparation seen in more elaborate examples.

What survives at Corragarrow is fragmentary, and its date remains unspecified in the available record. But the alignment of the two exposures, and the band of wood chips running between them, gave archaeologists enough to conclude that they were likely looking at the remains of a single trackway rather than unrelated deposits. It is a slight thing, in the physical sense, but that modesty is part of what makes it interesting: not every ancient road was a feat of engineering. Some were simply a farmer's practical answer to a wet field.
