It is one of several such structures recorded in this part of the Irish midlands, and its very existence raises questions about the communities who built it and the journeys they needed to make across terrain that would otherwise have swallowed them whole.

The structure is what is known as a togher, a word from the Irish tóchar, meaning a causeway or trackway laid across boggy or marshy ground. This particular example runs for 105 metres in a north-east to south-west orientation, and it was built in two layers. The upper surface, the superstructure, was made from hazel twigs and leaves, providing a workable surface underfoot. Beneath that, transverse bundles of hazel and ash brushwood formed a supporting mat, distributing weight across the soft ground below. This class 2 designation refers to the construction method and materials, distinguishing it from more elaborate plank roads such as the famous Iron Age trackway also found at Corlea, which used massive oak planks and is now partially preserved in a dedicated visitor centre nearby. The brushwood togher represents a more modest, practical approach, the kind of infrastructure that ordinary movement through a wet landscape required.
