Tourists driving between Dublin from Wicklow and Wexford are facing years of road works and delays as plans emerge for a third lane and junction closures along sections of t
he road between Loughlinstown Hospital and Ashford.
Traffic on the M11/N11 road has risen dramatically since the Glen o’ the Downs road was widened to a dual carriageway, going from 25,600 vehicles a day in 1999, to 53,000 last year.
Traffic volume grows to 78,000 when it is counted north of Bray, on the M11 just inside the Co Dublin border. Some 20,000 of these vehicles are from Co Wexford, about 14,000 of them recorded north of Gorey.
Wicklow County Council is set to start work on a parallel service road to the southbound lane of the N11 at Kilmacanogue, in a matter of weeks.
