Rossbeigh is situated on the southern shore of Dingle Bay with cliff stabilisation and erosion issues occurring over the years. The design required the development of innovative engineering solutions to address and manage the very challenging geotechnical and topographical conditions, traffic management and drainage control issues, taking due account of the considerable health and safety risks both for road users and for construction personnel. The solution depended on the development of innovative construction techniques in an extremely difficult site, carried out on a very steep slope with a level difference of 22 metres over the extent of the works. The construction method required geogrid reinforced earth and soil nailing techniques for structural stability. The embankment surface consisted of a topsoil layer temporarily supported by biodegradable matting and a light steel mesh to support vegetation.
