Toghers, as these bog roads are known, were constructed across wet and treacherous terrain to allow people and animals to pass where the ground would otherwise have been impassable. The example at Baunmore is a class 2 togher, meaning it was built to a relatively substantial standard, running 59 metres in length and nearly three and a half metres wide, with a depth of just over 11 centimetres. Its construction follows a logic that is simple but effective: a lower layer of brushwood laid down to stabilise the soft ground beneath, topped by heavier roundwood timbers to create a firm, walkable surface.

The road runs north to south, suggesting it was connecting two points of practical significance rather than following the contours of the land by accident. It came to light in 1995, when the Irish Archaeological Wetland Unit at University College Dublin identified it during a pilot survey of the Littleton Works, a systematic effort to record archaeological features within the bogs of the Irish midlands and their fringes before drainage or cutting could destroy them. Bog environments are unusually good at preserving organic materials, including wood, because the acidic, oxygen-poor conditions slow decay dramatically, which is why structures like this one can survive for centuries or even millennia while equivalent features built on dry land have long since vanished.
