bridge

Single-arch road bridge over river, "unfinished" 1829; extant 1838. Creeper- or ivy-covered walls with cut-limestone stringcourses supporting parapets having lichen-covered cut- or hammered limestone coping. Single round arch with drag edged rock faced limestone ashlar voussoirs. Sited spanning Abhainn Ghleann Lasra [Glenglassera River] with overgrown banks to river.

A bridge erected under the supervision of Alexander Nimmo (1783-1832), Engineer to the Western District (appointed 1822; replaced 1831), regarded as an important component of the early nineteenth-century civil engineering heritage of Contae Mhaigh Eo [north County Mayo] with the architectural value of the composition confirmed not only by the rock faced dressings demonstrating good quality workmanship, but also by the lofty "sweep" of the arch making a dramatic visual statement at a crossing over the minor Abhainn Ghleann Lasra [Glenglassera River]: meanwhile, a discreet benchmark remains of additional interest for the connections with cartography and the preparation of maps by the Ordnance Survey (established 1824).
