This is not a road in any monumental sense; it is a togher, a trackway made from bundled brushwood laid across waterlogged ground to allow people to move through terrain that would otherwise swallow them. What makes this particular example arresting is its age. Radiocarbon dating places its construction somewhere between 3329 and 2910 BC, pushing it deep into the Neolithic period, long before the Bronze Age technologies more commonly associated with Irish bog roads.

The trackway was first recorded in 1989, when the exposed section measured just over four metres in length and less than a metre wide. A decade later, a more thorough inspection found that it extended across nine fields for a total length of around 180 metres, with a width ranging from 0.7 to 1.7 metres. The construction was modest but deliberate: tightly packed parallel brushwood, mostly thin material between one and three centimetres in diameter, laid in one or two layers along the line of travel. Small pegs, around three centimetres across, were used to hold the structure in place. At one point in the trackway the original edging was clearly preserved, two parallel roundwood timbers about 1.2 metres apart defining the margins of the path, with a transverse piece of brushwood laid across them. The orientation shifted slightly as it moved across the fields, running roughly east-north-east to west-south-west for much of its length before angling more towards north-east to south-west. Corlea is already well known for its later and more substantial Iron Age plank road, but this earlier trackway is a quieter, less celebrated presence in the same landscape, built by people whose intentions and destinations remain entirely unknown.
