Not a road in any grand sense, but a togher, an ancient trackway laid across wet or boggy ground to make passage possible where it would otherwise be treacherous. This particular example belongs to what archaeologists classify as a class 3 togher, one of the simpler forms of construction, in which a base layer of brushwood laid lengthways provides a platform for a loose scattering of roundwood on top.

The structure runs east to west, and the wood used to build it was mostly birch and hazel, two species that would have been readily available from scrubby woodland growing at the bog's edge. Neither is especially durable in open conditions, but submerged in the anaerobic environment of a raised bog, organic material can survive for centuries or even millennia without rotting away. Toghers like this one were working infrastructure, built by people who needed to cross difficult ground, perhaps to reach grazing land, cut turf, or move between settlements. The modesty of the construction is itself informative: this was not a prestige causeway but a practical solution, put together with whatever timber was close to hand.
