What makes it quietly notable is the suspicion that it may not be entirely modern in origin. Beneath the gravel surface, or at least informing its course, there may lie an older trackway, possibly a togher.

A togher is a type of ancient roadway built across boggy or waterlogged ground, typically constructed from timber planks, brushwood, or compacted material laid directly onto the soft surface to allow safe passage. Such routes were essential in a landscape that would otherwise have been impassable for much of the year, and examples have been found across Irish bogs dating back thousands of years. The Ballinderry road follows a line that may preserve the memory of one of these older crossings, though the bog here has been cut so extensively that any underlying structure, if it exists, would be difficult to trace. The intensively harvested peat on either side of the road gives the whole scene a stripped, industrial quality that makes the persistence of a throughway across it all the more striking.
