Togrars of this kind were once essential infrastructure across Ireland's midlands and western counties, constructed over centuries ranging from the Bronze Age through to the early medieval period, and sometimes beyond. This particular example is classified as a class 3 togher, a designation that reflects its construction method and preserved condition, though the precise details of its materials, dimensions, and dating remain largely unpublished at present.

Togrars survive in Ireland because peat bogs are exceptional preservers of organic material, keeping wood, leather, and even human remains intact for thousands of years. The act of building one was no small undertaking. Timbers had to be felled, split, and laid in careful sequence, sometimes pegged into the soft ground, to create a surface that could bear the weight of people, animals, and goods. The townland of Carta sits within a landscape that would have required exactly this kind of engineering, where the practical demands of moving across a boggy terrain shaped how communities connected with one another and with markets, churches, and seasonal pastures. A class 3 classification generally indicates a togher of modest but recognisable structural complexity, distinguishing it from simpler brushwood deposits while falling short of the most elaborate multi-layered roadways known from sites like the Corlea Trackway in County Longford, which dates to 148 BC and is one of the largest Iron Age bog roads in Europe.
