The post-medieval trackway at Ballycasey More in County Clare managed something slightly different: it survived long enough underground to be properly recorded before disappearing again, this time beneath development ground.

The road came to light in 1998, excavated under licence ahead of a land sale for development. What emerged was a substantial linear feature running more than 170 metres on a northwest to southeast orientation, cut directly into the natural ground. It was not simply a worn path but a deliberately engineered route, with an earthen bank raised along its western side, roughly four metres wide and standing about 0.6 metres high. The eastern side was handled differently, scarped rather than banked, meaning the ground was cut back and shaped to form a sloped edge approximately three metres wide and 0.45 metres high. Together these features gave the trackway a clear, managed profile, more like a raised causeway or holloway than a casual track. A holloway is a road or path that over time, through repeated use and erosion, has been worn below the level of the surrounding land; here the combination of scarping and banking suggests deliberate construction rather than gradual wearing. The date places it in the post-medieval period, after the late sixteenth century, when rural road-making in Ireland was becoming more formalised, though the specific circumstances of who built it or why have not been established from the excavation.
