N4 Dublin to Sligo

This road is intended to provide a high quality link between Sligo and Dublin.

Already major sections of this route have been upgraded to motorway or high quality dual carriageway standard. Journey times have been substantially reduced along the route while safety has also noticeably improved.

In addition major funding has been allocated to the route to improve junctions, relay road surfaces and improve overall standards and safety.
