Motorists across Dún Laoghaire-Rathdown should expect a busier week on the roads, with fresh closures, reduced speed limits, and multiple resurfacing projects in progress. This Dublin news update covers the key traffic changes from Saturday 27 June to Friday 3 July 2026, helping commuters, local residents, and businesses plan journeys with fewer disruptions.
Several major routes are affected this week, particularly around Dundrum, Blackrock, Dún Laoghaire, Kilternan, and Cherrywood. Temporary traffic measures are also tied to longer-term infrastructure and housing projects that are expected to shape future travel patterns in the county.
Dublin news: speed limits and major traffic changes this week
One of the most important updates is on the M11 northbound, where a temporary 60km/h speed limit remains in force from the county boundary near Junction 7 to Junction 5. The measure, running from 22 June to 17 July 2026, is in place to support resurfacing works.
Meanwhile, the Wyattville Link Road continues to operate under a temporary 50km/h speed restriction on the westbound section between Cherrywood Avenue and the M50 southbound slip road. These controls are linked to the ongoing underpass construction and are expected to remain until 30 November 2026, or until the works finish.

- Fitzgerald Park Road, Dún Laoghaire: closed on 28 June from 2pm to 5pm for a community event

Resurfacing, footpath works, and local delays
Beyond the headline closures, a wider programme of roadworks is underway across the county. These include resurfacing, footpath improvements, rehabilitation work, and traffic-calming measures in several residential and commuter-heavy areas.
Locations impacted this week include:
- 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 operations are scheduled between 10am and 4pm to reduce peak-time disruption, though temporary lane restrictions and Stop/Go traffic systems may still slow journeys.
Dundrum development and active travel projects continue
A significant long-term factor in this Dublin news roundup is the start of work on Dún Brí, the new development on the former Central Mental Hospital site in Dundrum. Early-stage works include demolition, utility preparation, and site setup. While most activity is being kept within the site boundary, construction traffic is expected to increase as the project advances.
This matters not only for local residents but also for wider Dublin business activity, as major housing and transport upgrades often influence commuting patterns, retail access, and local services.
At the same time, active travel schemes remain in progress, including works on Glenageary Road Upper, Mounttown Road, and the Dodder Greenway connection at Ely’s Arch. Safe Routes to School projects are also moving ahead in Dundrum and Blackrock, with pedestrian access maintained throughout.

What drivers should do before travelling
To reduce stress and avoid unnecessary delays, road users should:
- Check routes before leaving
- Allow extra time during daytime travel

This Dublin news update shows just how active the county’s road network is this week, with improvement works, school-route upgrades, and development-related traffic all happening at once. The key takeaway is simple: plan ahead, expect delays in several south Dublin locations, and keep an eye on changing traffic conditions throughout the week.
