It belongs to a category known as a togher, the Irish term for a timber trackway or causeway laid across boggy or marshy terrain to allow passage where the ground would otherwise be impassable. These structures were built across many centuries, and the peat that swallowed them has, paradoxically, preserved their timbers far better than open air ever could.

This particular togher is classed as a Class 3 example, a designation referring to its construction type within a typology developed to categorise the considerable variety of these bog roads found across Ireland. It was recorded during a field survey in 1988, and its orientation runs roughly northeast to southwest. The reference to Raftery 1990 points to the work of Barry Raftery, the archaeologist whose research into Irish bog roads and wetland archaeology brought systematic attention to these sites during the latter decades of the twentieth century. The survey work at Annaghbeg formed part of a broader effort to document such features before drainage, turf-cutting, or other land use could disturb or destroy them entirely.
