Drivers, cyclists and pedestrians across south Dublin should allow extra time this week as multiple road closures, utility projects and traffic restrictions take effect. This Dublin news update covers the main travel changes in Dún Laoghaire-Rathdown from 12 to 18 September 2026.
The information was published by Dún Laoghaire-Rathdown County Council and was correct at 4pm on 10 September. Emergency works may arise without notice, so travellers should follow local signage and check conditions before setting out.
Dublin news: key traffic restrictions this week
Wyattville Link Road
A temporary 50km/h speed limit remains 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 as part of the Beckett Link Road Project and is expected to continue until 30 November 2026, or until works finish earlier.
Mounttown Road Lower
Mounttown Road Lower remains subject to a temporary one-way system. Vehicles can travel northbound from Kill Avenue towards York Road, while southbound traffic must use signed diversions. The arrangement forms part of the Dún Laoghaire Central Active Travel Scheme, which is expected to be completed by the end of October.
Planned road closures and local diversions
Several proposed closures are entering the consultation or planning stage:
- Brides Glen Road, Shankill: a proposed extension from 26 September to 28 November for a new watermain between Rathmichael Road and Mullinastill Road.
- Killiney Hill Road: a proposed closure between Victoria Road and Military Road from 29 September to 1 October, 8am–6pm daily, for gas works.
- Silchester Road, Glenageary: a short closure near Silchester Crescent on 9 October, from 10am to 4pm, for reinstatement works.
Pedestrian and local access will generally be maintained where stated, with diversion routes signposted. Residents wishing to submit observations should meet the deadlines listed by the council.
Additional works affecting journeys
Utility, reinstatement and connection works are scheduled across Blackrock, Dundrum, Foxrock, Dalkey, Monkstown, Sandycove, Glenageary, Mounttown and Roebuck. Locations include Ballinteer Road, Carysfort Avenue, Newpark Road, Coliemore Road, Kilmacud Road Upper and Oliver Plunkett Road. Temporary lights, Stop/Go systems and lane restrictions may be introduced.
Active travel and school safety projects
Construction continues at the Dodder Greenway’s Ely’s Arch project. Dodder Road Lower is permanently one-way westbound from Orwell Road towards Ely’s Arch, while Stop/Go controls will operate at the Orwell Road and Dodder Road Lower junction on 15 September.
Major construction at Holy Cross National School, Carysfort National School, Holy Family National School and The Harold School is substantially complete. Minor snagging remains, with limited traffic management possible.
The council is also proposing a signal-controlled pedestrian crossing at the N11 Cornelscourt junction, including improved signals, footpaths, kerbing, tactile paving and signage.
