This one is classified as a class 3 togher, a category that typically indicates a relatively modest construction, laid down using split or round timbers placed transversely across the soft ground rather than the more elaborate jointed frameworks of the higher classes. What makes such structures quietly remarkable is not their scale but their purpose and their survival: built to solve an everyday problem of movement through a waterlogged landscape, they were swallowed by the very bog that now preserves them.

This particular togher was noted during a field survey in 1988, running on a north-east to south-west orientation across the bog. The observation was communicated by B. Raftery, one of Ireland's foremost authorities on bog roads and prehistoric trackways, whose work across Irish wetlands helped establish the systematic study of these structures. Toghers are found across many Irish counties, with some dating back thousands of years, though the precise age of the Cloonfiugh example is not recorded. The bogs of the Irish midlands were, for much of prehistory and into the early medieval period, significant barriers to travel, and trackways like this one represent considerable communal effort to maintain routes between settlements, grazing lands, and areas of resource.
