Traffic and roadworks updates for Dún Laoghaire-Rathdown residents
Motorists across Dún Laoghaire-Rathdown are advised to anticipate delays as various infrastructure projects and essential utility works continue throughout the county this week. Local authorities have implemented several diversions and temporary traffic management measures to facilitate these ongoing developments.
Commuters navigating Dún Laoghaire-Rathdown should prepare for significant traffic adjustments between 12 and 18 September 2026. A 50 km/h speed limit remains enforced on the westbound Wyattville Link Road to support the Beckett Link Road Project, with these restrictions expected to persist until late November. Furthermore, the one-way system on Mounttown Road Lower continues to facilitate the Dún Laoghaire Central Active Travel Scheme, with northbound traffic flow prioritised until the end of October.
Several upcoming road closures have been proposed to accommodate utility infrastructure. GMC Utilities has requested an extension for the closure of Brides Glen Road in Shankill through to late November for watermain works, while Gas Networks Ireland plans a short-term closure of Killiney Hill Road between 29 September and 1 October. Additionally, a brief closure is scheduled for Silchester Road on 9 October to allow for permanent reinstatement works. Residents may submit observations regarding these proposals to the Council’s Senior Engineer by the specified deadlines.
Active travel and infrastructure projects remain a focal point for the region. Construction continues at the Dodder Greenway, with Dodder Road Lower now operating as a permanent one-way route westbound. Motorists should also note that ESB ducting works at Galloping Green are ongoing, impacting local bus and cycle lanes. To ensure a smooth journey, road users are encouraged to allow extra travel time and adhere strictly to all signposted diversions and temporary traffic management systems currently in operation.
