The togher, a timber trackway of the kind laid across soft or waterlogged ground to allow passage through otherwise impassable terrain, was oriented northeast to southwest, and that single fact is very nearly all that is known about it. It was destroyed before it could be recorded, leaving behind only its classification as a class 3 togher and its coordinates in the landscape.

Corlea is already known to archaeologists as an extraordinary site. A nearby trackway, constructed around 148 BC during the Iron Age, is one of the largest bog roads ever uncovered in Europe and is now preserved in a dedicated interpretive centre. Toghers like it were typically built from split oak planks or brushwood laid over parallel runners, engineered to carry people, animals, and perhaps goods across the midland bogs that would otherwise have been seasonal barriers to movement. The class system used to categorise such roads relates to their construction type and scale. This particular togher's classification suggests a specific method of build, though without excavation records, the details remain out of reach. What is clear is that the bogs of this part of Longford were crossed and re-crossed over millennia, and each new drainage scheme or turf-cutting operation risks uncovering, and destroying, further evidence of that traffic.
