Motorists in south Dublin are being urged to plan ahead as a fresh round of road closures, reduced speed limits and resurfacing works affect key routes across Dún Laoghaire-Rathdown. This latest Dublin news update covers the main traffic changes in place from Saturday, 27 June to Friday, 3 July 2026, with advice for commuters, residents and local visitors.
Several schemes tied to road safety, resurfacing and active travel are moving ahead this week, meaning delays are likely at different times of the day. Drivers should allow extra time, especially when travelling through Dundrum, Blackrock, Dún Laoghaire and Kilternan.
Dublin news: Main traffic changes drivers should know
Temporary speed limits in place
A reduced 60km/h speed limit is active on the northbound M11 between the county boundary near Junction 7 and Junction 5. The measure is in place from 22 June until 17 July 2026 to support resurfacing works.
On the Wyattville Link Road, a temporary 50km/h limit remains on the westbound section from Cherrywood Avenue to the Cherrywood M50 southbound slip road. That restriction is linked to underpass construction and is expected to remain until 30 November 2026, or until works are completed.

Where additional roadworks are happening
Road and footpath improvement works are also scheduled across several neighbourhoods. Among the areas impacted are:
-
York Road, Dún Laoghaire
-
Ballybrack Village
-
Churchtown Road Upper
-
Ballybetagh Road
-
Killiney Avenue

Frascati Park, Blackrock
Short-term works are also expected in Stillorgan, Shankill, Dundrum, Dalkey and Deansgrange. Most of these projects are due to take place between 10am and 4pm, often using Stop/Go systems or temporary lane restrictions.
Dundrum development and local travel impact
Separate from the weekly roadworks programme, enabling works have started on Dún Brí, the new housing development on the former Central Mental Hospital site in Dundrum. The project is expected to deliver a significant number of affordable and social homes, making it a notable part of the wider Dublin business and housing picture.
While most activity is being contained inside the site, construction traffic is expected to increase over time. Traffic management, road cleaning and safety controls will be introduced as required. Standard working hours are 7am to 7pm Monday to Friday and 8am to 2pm on Saturdays.

Active travel schemes continue across the county
Ongoing active travel works remain in progress on Glenageary Road Upper and Mounttown Road as part of the Dún Laoghaire Central Active Travel Scheme. Traffic management is active at some junctions, while work also continues on the Dodder Greenway at Ely’s Arch.
Safe Routes to School upgrades are also continuing in Dundrum, Blackrock and other local areas. In most cases, works are scheduled outside peak traffic periods, and pedestrian access is being maintained.
What drivers should do now
For anyone travelling through the county this week, the key message from this Dublin news update is simple: expect some disruption and prepare in advance.
-
Leave extra travel time
-
Watch for diversion signage
-
Slow down near work zones
-
Be alert for temporary traffic controls
As more infrastructure and safety projects move forward, short-term disruption is likely to remain part of the journey. Still, these upgrades are designed to improve road safety, local access and long-term travel conditions across the area.
