Drivers, cyclists and pedestrians travelling through south Dublin should plan ahead this week as road closures, utility works and temporary traffic systems affect several routes across Dún Laoghaire-Rathdown. This Dublin news update covers the main changes scheduled between Saturday, 19 September, and Friday, 25 September 2026, based on information issued by the county council.
Key Dublin traffic changes this week
A temporary 50 km/h limit remains in force westbound on 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 2026, or until the project finishes.
Motorists should also expect delays around active construction and utility sites, including:
- Camberley Oaks in Dundrum, where a pedestrian crossing and speed ramp are being installed.
- Enniskerry Road at Struan Glen, where Uisce Éireann infrastructure work continues.
- Ashlawn Park in Loughlinstown, where resurfacing and footpath maintenance are under way.
- Dundrum Road and Shanacoumha Cul-de-Sac, affected by ESB trenching and ducting.
- Sydney Avenue, George’s Avenue and Frascati Park in Blackrock, where rehabilitation works continue.
Closures and diversions to watch
Brides Glen Road in Shankill remains closed for watermain installation, with a proposed extension running from 26 September to 28 November. Killiney Hill Road is scheduled to close between Victoria Road and Military Road from 29 September to 1 October for gas works. Local and pedestrian access will generally be maintained where stated, but road users should follow signed diversions.
Mounttown Road Lower continues to operate as a northbound-only route between Kill Avenue and York Road. The arrangement forms part of the Dún Laoghaire Central Active Travel Scheme and is expected to remain until the end of October.
Active travel and sustainable transport projects
Work is continuing on the Dodder Greenway – Ely’s Arch Project. Dodder Road Lower is permanently one-way westbound between Orwell Road and Ely’s Arch, while new two-way cycle lanes are expected to partially open during autumn 2026.
Construction has also been substantially completed at several Safe Routes to School locations, including Holy Cross National School in Dundrum, Carysfort National School in Blackrock and Holy Family National School in Monkstown. Minor snagging works may still require short-term traffic management.

The council is also proposing a signal-controlled pedestrian crossing at the N11 Cornelscourt junction. Proposed improvements include upgraded signals, footpaths, kerbing, tactile paving, road markings and signage, with the aim of improving accessibility and safety.
