Motorists across south Dublin are being urged to plan carefully this week as a fresh round of road closures, reduced speed limits and local traffic controls comes into effect. This Dublin news update covers the main disruptions across Dún Laoghaire-Rathdown from late June into early July, including resurfacing works, school route upgrades and longer-running infrastructure projects.
Among the most important changes is a temporary 60km/h limit on the northbound M11 between the county boundary near Junction 7 and Junction 5, in place from 22 June to 17 July 2026 to support resurfacing works. On the Wyattville Link Road, a 50km/h restriction remains active westbound from Cherrywood Avenue to the Cherrywood M50 southbound slip road while underpass construction continues.

Where roadworks are happening
In addition to full closures, a wide range of improvement works are underway across the county. Drivers may encounter Stop/Go systems, temporary lane restrictions and slower traffic in areas such as York Road in Dún Laoghaire, Ballybrack Village, Churchtown Road Upper, Ballybetagh Road, Killiney Avenue and Frascati Park in Blackrock.
Short-term works are also planned in Stillorgan, Shankill, Dundrum, Dalkey and Deansgrange. Most activity is scheduled between 10am and 4pm to reduce pressure during peak commuting periods.
Dundrum development traffic impact
Work has now started on Dún Brí, the major new housing development on the former Central Mental Hospital site in Dundrum. The project is set to deliver a large number of affordable and social homes, making it significant not only for local planning but also for wider Dublin business and housing conversations.
Initial enabling works include demolition, utility setup and site preparation. While much of the activity remains within the site boundary, construction traffic is expected to rise over time. Residents can also expect road safety controls and cleaning measures as the project progresses.

Active travel projects continue across the county
Ongoing transport and mobility schemes are also shaping movement across the area. The Dún Laoghaire Central Active Travel Scheme continues on Glenageary Road Upper and Mounttown Road, while the Dodder Greenway Ely’s Arch project remains active with some traffic delays.
Safe Routes to School works are continuing in Dundrum, Blackrock and other locations, with pedestrian access being maintained throughout. These schemes are designed to improve safety, reduce congestion near schools and support more sustainable travel choices.
What drivers should do now
If you are travelling through the county this week, it is worth taking a few practical steps:
- Allow extra time for local and regional trips
- Follow official diversion signs rather than relying only on sat-nav
- Drive carefully near workers, narrowed lanes and temporary signals
- Expect disruption around Dundrum, Blackrock and Dún Laoghaire in particular
This Dublin news roundup shows how road maintenance, housing construction and active travel investment are all converging at once. For anyone commuting, managing deliveries or tracking local change, staying ahead of these updates is the best way to avoid delays and travel more safely.
