Drivers, cyclists and pedestrians travelling through south Dublin should allow extra time this week as road closures, diversions and utility works affect several routes across Dún Laoghaire-Rathdown. This Dublin news update covers the main traffic arrangements scheduled from Saturday, 12 September, through Friday, 18 September 2026.
The information was accurate at 4pm on Thursday, 10 September. Emergency works may arise without advance notice, so road users should follow on-site signs and traffic-control instructions.
Dublin traffic changes to know this week
Wyattville Link Road speed restriction
A temporary 50km/h limit remains on the westbound Wyattville Link Road between Cherrywood Avenue and the Cherrywood M50 southbound slip road. The restriction supports construction of the underpass forming part of the Beckett Link Road Project and is expected to continue until 30 November 2026, or until construction finishes.
Mounttown Road Lower one-way system
Mounttown Road Lower continues to operate as a temporary one-way route. Northbound traffic can travel from Kill Avenue towards York Road, while southbound drivers must use the signed diversion. The arrangement is linked to the Dún Laoghaire Central Active Travel Scheme and is expected to remain until the end of October.
Planned road closures and public notices
Several proposed closures require local observations before work begins:
- Brides Glen Road, Shankill: A proposed extension from 26 September to 28 November would support installation of a new large-diameter watermain. Submissions are due by noon on 22 September.
- Killiney Hill Road: Gas Networks Ireland has applied for a daytime closure between Victoria Road and Military Road from 29 September to 1 October. Submissions close at noon on 16 September.
- Silchester Road, Glenageary: A short closure near Silchester Crescent is proposed for 9 October, from 10am to 4pm. Submissions are due by noon on 23 September.
Pedestrian and local access is expected to be maintained where stated, with diversions signposted.
Where utility and reinstatement works are scheduled
Temporary traffic lights, Stop/Go controls, lane restrictions or local diversions may affect roads in Blackrock, Dundrum, Foxrock, Dalkey, Monkstown, Sandycove, Sandyford, Glenageary and Dún Laoghaire. Notable works include utility activity on Ballinteer Road, Carysfort Avenue, Galloping Green North, Newpark Road and Roebuck Road.
Reinstatement works are also scheduled on routes including Coliemore Road, Kilmacud Road Upper, Sandyford Road, Avoca Avenue, Meadowland Avenue and Oliver Plunkett Road. ESB cable and drinking-water connection works will continue at several locations throughout the week.
Active travel and school-zone updates
Construction continues at the Dodder Greenway’s Ely’s Arch Project. Dodder Road Lower is permanently one-way westbound between Orwell Road and Ely’s Arch, while Stop/Go traffic management is planned at the Orwell Road and Dodder Road Lower junction on 15 September.
Major works at Holy Cross National School, Carysfort National School, Holy Family National School and The Harold School are substantially complete. Minor snagging may still require temporary traffic controls, although significant disruption is not expected.
The Council is also proposing a signal-controlled pedestrian crossing at the N11 Cornelscourt junction, including improvements to signals, footpaths, kerbing, tactile paving, road markings and signage.
