N4 Collooney to Castlebaldwin, Sligo

    National Roads

    The N4 is the main Inter-Urban link between Dublin and the North West Region. The N4 Collooney to Castlebaldwin Road Scheme was included in the Building on Recovery: Infrastructure and Capital Investment Capital Plan 2016-2021, as a key priority in the roads programme which supported economic growth. The Plan identified it as one of the “critical gaps” in our existing infrastructure, which needed to be upgraded.

    We were appointed to provide consultancy services for advanced works, procurement, construction supervision and close out of the realignment of the N4 section between Collooney to Castlebaldwin. This scheme is 14.5km in length of Type 2 Dual Carriageway, and just under 1km of Single Carriageway on the National Road Network, linking the existing N4 dual carriageway at Collooney to the Curlews By-Pass, just south of Castlebaldwin village.

    As part of the project, a new three-km cycleway from Toberbride has been constructed and joins the existing N4 at Doorly, which has improved conditions for pedestrians and cyclists wishing to access local services.
