Sligo County Council, in conjunction with Transport Infrastructure Ireland, are seeking to carry out a topographical survey for the design stage of the N59 Corhawnagh to Crockacullion Road Improvement Scheme. The total area covered by the proposed survey is approximately 151ha. This survey will provide the background information to undertake the design of the main alignment and side road alignments. This will include new structures, earthworks, drainage, pavement, accommodation works, fencing, utility diversions, and other ancillary works.
