• Future: A separate project is in planning to provide 14 km of dual carriageway from Rathnew to Arklow. This project has been approved by An Bord Pleanala and the tender process for the construction phase has commenced. Once completed, dual carriageway or motorway would extend from Donnybrook near central Dublin to south of Clogh in County Wexford. No road tolls are planned. Land acquisition and site fencing is completed and it is anticipated construction will begin on this section in June 2012.

A further project is in planning to provide a 27 km motorway bypass around Enniscorthy and also connecting the M11 to the N30. Currently, the passage of traffic through the town is restricted by the narrow streets and the two bridges which connect the town across the River Slaney.

Initial planning is underway to bypass Oilgate by building a new dual carriageway N11 from the end of the future Enniscorthy bypass to the N25 near Wexford Town. A new section of N25 will complete the up-grade of Euroroute 01 between the M50 and Rosslare Harbour.

If all these were completed as planned, there would be no single carriageway sections of the N11 left.

On 30 September 2008, the Department of Transport proposed that the dual carriageway sections from Ashford to south of Rathnew, and from north of Arklow to south of Gorey, be reclassified as motorway under the Roads Act 2007. The Statutory Instrument for these reclassifications was passed on 2 July 2009 and came into effect on 28 August 2009. There are now three sections of M11 motorway forming part of the N11 route.
