Known as toghers, these are timber trackways built across soft or waterlogged ground, a practical solution to the problem of crossing bogland that Irish communities employed from the Bronze Age onwards. In Killoran townland alone, a field survey identified twenty-nine of them, a concentration that suggests this was once a well-travelled and carefully managed crossing point through terrain that would otherwise have been impassable.

The survey, carried out by Gowen in 1999, revealed considerable variety in how these toghers were put together. Fifteen were constructed entirely from brushwood, the simplest approach, essentially laying bundled branches flat to spread the weight of foot traffic. The remainder combined brushwood with roundwood timbers, and three showed evidence of pegs or stakes driven into the ground to hold the structure in place. Radiocarbon dating of one togher returned a date range of AD 1024 to 1162, placing it firmly in the early medieval period, when such routes would have connected farms, monasteries, and market settlements across the Irish midlands. Wood identification carried out on thirteen of the toghers found alder, ash, birch, elm, hazel, holly, and mountain ash all represented, though ash and hazel were the most common choices. This is not surprising; both are flexible, relatively fast-growing, and were widely available in early medieval woodland. The selection of species was almost certainly practical rather than incidental, reflecting what woodworkers knew would hold up under repeated use in wet conditions.
