Drivers, cyclists and pedestrians travelling through south Dublin should plan ahead as roadworks, closures and temporary traffic controls affect several routes in Dún Laoghaire-Rathdown from 12 to 18 September 2026. The latest Dublin news includes changes linked to water, gas, utility and active-travel projects.
Key traffic changes across south Dublin
A temporary 50 km/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 Wyattville Link Road underpass as part of the Beckett Link Road Project and is expected to remain until 30 November 2026, or until works finish.
Mounttown Road Lower also continues to operate under a temporary one-way system. Vehicles can travel northbound between Kill Avenue and York Road, while southbound traffic must use signed diversion routes. This arrangement is connected to the Dún Laoghaire Central Active Travel Scheme and is expected to continue until the end of October.
Planned closures requiring public feedback
Several proposed closures are awaiting observations:
- Brides Glen Road, Shankill: A proposed extension from 26 September to 28 November would allow installation of a large watermain between Rathmichael Road and Mullinastill Road. 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. Feedback is due by noon on 16 September.
- Silchester Road, Glenageary: A short closure near Silchester Crescent is proposed for 9 October, from 10am to 4pm. Submissions close at noon on 23 September.
Roadworks, diversions and utility activity
Temporary traffic lights, lane restrictions and Stop/Go controls may affect routes including Ballinteer Road, Carysfort Avenue, Galloping Green North, Blackrock’s Newpark Road area, Foxrock, Dalkey, Kilmacud Road Upper, Sandyford Road and several residential streets.
ESB cable and connection works are scheduled on the R837, Stonebridge Road, Dundrum Road, Shanacoumha Cul-de-Sac Road, North Avenue and Roebuck Road. Reinstatement works are also planned at multiple locations in Dún Laoghaire, Monkstown, Glenageary and Sandycove.

Active travel projects continue
Work is progressing on the Dodder Greenway – Ely’s Arch Project. Dodder Road Lower is permanently one-way westbound from Orwell Road towards Ely’s Arch, while Stop/Go management will operate at the Orwell Road and Dodder Road Lower junction on 15 September.
Construction at several Safe Routes to School locations is substantially complete, including Holy Cross National School in Dundrum, Carysfort National School in Blackrock and Holy Family National School in Monkstown. Minor finishing work may still require temporary controls.
Proposed Cornelscourt pedestrian crossing
Dún Laoghaire-Rathdown County Council is proposing a signal-controlled crossing at the N11 Cornelscourt junction. Planned improvements include upgraded signals, footpaths, kerbing, tactile paving, road markings and signage, supporting safer access for pedestrians, cyclists and public transport users.

What road users should do
- Allow additional time for journeys through affected areas.
- Follow diversion signs, temporary signals and instructions from traffic controllers.
- Check routes before travelling, particularly during utility and reinstatement works.
- Remember that emergency road repairs may arise without advance notice.
The main takeaway from this week’s Dublin news is simple: planned ahead travel will help reduce delays while major infrastructure and active-travel projects continue across the county.
