Drivers, cyclists and pedestrians should plan carefully this week as several closures, diversions and construction projects affect travel across Dún Laoghaire-Rathdown. This Dublin news update covers the main traffic measures scheduled from Saturday, 24 October, to Friday, 30 October 2026.
The information was issued by Dún Laoghaire-Rathdown County Council and was current at 4pm on Thursday, 22 October. Emergency roadworks may arise without notice, so commuters should allow additional time and follow signs, temporary signals and instructions from traffic management crews.

Night works are planned around Rock Road, Stillorgan Road, Mount Merrion Avenue and N11 junctions, while Wyattville Road will have night-time surface water gully replacement works.
Other scheduled projects include footpath and resurfacing works at Ashlawn Park in Ballybrack, pedestrian crossing improvements at Mart Lane and Bray Road, and crossing upgrades near the Leopardstown Link Road Mastercard entrance. Further traffic signal and Stop/Go arrangements are expected at Blackrock Town Centre on 28 October.
Utility and reinstatement works are also listed for Sandyford, Dún Laoghaire, Blackrock, Stillorgan, Deansgrange, Windy Arbour and Foxrock.
Active travel and school-zone projects

Work is also continuing on the Dodder Greenway’s Ely’s Arch project at the Orwell Road and Braemor Park and Orwell Road and Dodder Road Lower junctions. Dodder Road Lower remains permanently westbound one-way from Orwell Road towards Ely’s Arch, with diversions used where necessary. Completion is expected by the end of 2026.
Safe Routes to School projects at Holy Cross National School, Carysfort National School, Holy Family National School and The Harold School are largely complete. Remaining works are mainly landscaping, surfacing or snagging, and pedestrian access will be maintained.
