History

Major improvements to the N18 route have been made over the past decade. Originally the route was a narrow single carriageway route that ran through all the main towns and villages between Limerick and Claregalway where the route terminates. The first improvements involved the dualling of the Limerick, Bunratty and Shannon route. The Newmarket on Fergus bypass opened in December 2002 and the Ennis bypass opened in 2007. Both were redesignated as motorway in August 2009. The Limerick Tunnel and phase II of the Limerick Southern Ring Road opened in July 2010 forming a continuous motorway dual-carriageway from the N/M18 to the M7 and M20 outside Limerick. On 12 November 2010 the €207 million Gort to Crusheen(M18) bypass was opened. The remaining single carriageway sections from Gort to Claregalway have been upgraded to motorway standard and were officially opened on 27 September 2017.
