Road — class 1 togher in Derraghan More,derrygowna

This roadway (L 960m; D 1.25m) consisted of large transverse oak planks, supported by longitudinal runners and secured by pegs. Excavated in 1957 by Rynne (NMI file I.A. 32/57), the orientation was recorded as approximately E-W and it was noted that areas of sticky clay appeared to have been purposely laid between the longitudinal timbers (av. diam. 0.1m). Large transverse planks (av. dims. L 3.6m; Wth 0.15m; D 0.2m) were laid across the longitudinal timbers and were held in place with sharpened stakes or pegs. Although largely destroyed by peat-milling, excavations in 1989 by Raftery (1990, 37-41) exposed a surviving portion of the togher (L 14m; Wth 4.5m max.). The structure appeared to be broadly similar to that described previously but with concentrations of brushwood (D 0.45m max.) more evident in the substructure; the orientation was recorded as ENE-WSW. This togher is comparable with the Iron Age road (LF022-058001-) at Corlea and is of similar date. Dendrochronological dating revealed a date of 156±9 BC (Q7931M). A portion of the togher inspected in 1999 by Dunne (1999) was found to be supported by a band of sandy/gravelly material.
