Drivers, cyclists and pedestrians should plan carefully before travelling through south Dublin this week. This Dublin news update outlines closures, diversions, speed restrictions and active travel works scheduled across Dún Laoghaire-Rathdown from Saturday, 24 October to Friday, 30 October 2026.
The council’s information was current at 4pm on Thursday, 22 October. Emergency roadworks may arise without notice, so motorists are advised to allow additional time and follow temporary signs and traffic controllers.
Dublin road closures and major diversions
Dublin Marathon traffic restrictions
The Irish Life Dublin Marathon will bring temporary closures on Sunday, 25 October, from 9.20am until 4.30pm. Affected roads include Clonskeagh Road, Roebuck Road, Foster’s Avenue, Stillorgan Road north of Foster’s Avenue and the route between the UCD Flyover and the Dublin City boundary. Diversion routes and traffic management will operate throughout the event.
Torquay Road and Brides Glen Road
Torquay Road in Foxrock will close between Leopardstown Road and Golf Lane from 27 October to 1 November, daily from 8am to 6pm, while gas works take place. Local and pedestrian access will remain available.
Brides Glen Road in Shankill remains closed between Rathmichael Road and Mullinastill Road until 28 November for a large watermain installation. Glenamuck Road in Carrickmines also remains temporarily closed between Brambledown and the Enniskerry Road junction.
Roadworks and speed limits to watch
A temporary 50km/h limit continues on the westbound Wyattville Link Road between Cherrywood Avenue and the Cherrywood M50 southbound slip road. The restriction supports construction of the Wyattville Link Road underpass and is expected to remain until 30 November, or until the work finishes earlier.
Night and daytime works are also planned around Rock Road, Stillorgan Road, Mount Merrion Avenue, the N11 junctions, Blackrock, Wyattville Road, Ashlawn Park, Mart Lane, Bray Road, Leopardstown Link Road and Killiney Hill Road. Temporary lights, lane restrictions and Stop/Go systems may cause delays.
- Water upgrade works continue around Sydney Avenue, Anglesea Avenue and Frascati Park.
- Blackrock Town Centre will have temporary traffic controls on 28 October.
- Utility works are scheduled in Sandyford, Dún Laoghaire, Stillorgan, Deansgrange, Windy Arbour and Foxrock.
Active travel and school-zone improvements
The Dún Laoghaire Central Active Travel Scheme is substantially complete, although localised snagging, landscaping and minor roadworks will continue until mid-November. Construction also continues at the Dodder Greenway’s Ely’s Arch project, with works around Orwell Road, Braemor Park and Dodder Road Lower. The latter remains permanently westbound one-way from Orwell Road towards Ely’s Arch, with completion 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 surfacing, landscaping and snagging works should cause limited disruption, while pedestrian access will be maintained.
