|Route outline (key)|
The N11 is the main route connecting Dublin to the south-eastern coastal region of Ireland. Large sections of it have been substantially upgraded to grade-separated dual carriageway, although there are still some bottlenecks to be overcome at the road's southern end.
The route (which originally began at O'Connell Bridge in the very centre of Dublin) has since 2012 started in Mount Merrion at the end-point of three routes, where it meets the R138 coming in from the north and the N31 from Dún Laoghaire. From here, the N11 heads out southeastward through suburbia. After some miles of steadily improving road, it meets the M50, becoming the M11 motorway for a few miles. The road from here is a modern high quality dual carriageway bypassing Bray and Wicklow and is now motorway until after Enniscorthy.
The bypass of Enniscorthy cost €400 million for a 27-km motorway bypass, which opened on 18th July 2019. Beyond Enniscorthy, it's a fairly flat run through the countryside towards the Wexford bypass. Halfway along the bypass, the N25 from New Ross arrives and takes over the last stretch of road down to Rosslare Harbour.
In Ireland's first numbering scheme, the route that was later to become the N11 was formed by the T7 from O'Connell Bridge, Dublin, to Enniscorthy, and the T8 from there to Wexford. In the latter town, the original route turned left immediately after crossing the River Slaney and followed what is today the R730, meeting the R769 (earlier, a part of the N25) by the station.
Some sections of the current M11 dual carriageway opened as bypasses of the N11, but were subsequently converted by statutory instrument, these include Ashford to Rathnew, the Arklow Bypass, and Arklow to Gorey.
