Motorists across Dún Laoghaire-Rathdown should expect another busy week on local routes, with fresh closures, reduced speed limits and active works affecting key commuter corridors. This Dublin news update covers the main traffic changes from Saturday 27 June to Friday 3 July 2026, helping drivers, residents and businesses plan journeys with fewer surprises.
The most notable speed restriction remains on the M11 northbound, where a temporary 60km/h limit is in force from the county boundary near Junction 7 to Junction 5 until 17 July as resurfacing continues. A separate 50km/h restriction also remains on the Wyattville Link Road westbound, between Cherrywood Avenue and the Cherrywood M50 southbound slip road, linked to underpass construction works expected to continue until late November.
Dublin news: main road closures and diversions this week
Several short-term closures are in place across the county this week, alongside longer-running disruptions already familiar to regular road users. Diversions are signposted, but delays are still likely during peak local movement periods.
- Kilmacud Road Upper, Dundrum – closed until Saturday 27 June between Dundrum Garda Station and Dundrum College for resurfacing linked to the Safe Routes to School programme.
- Fitzgerald Park Road, Dún Laoghaire – closed on Sunday 28 June from 2pm to 5pm for a community family event.
- Convent Road, Blackrock – closed from Monday 29 June to Friday 3 July for resurfacing works.
Ongoing closures also continue at Enniskerry Road in Kilternan, Knapton Road in Dún Laoghaire and the westbound Wyattville Link Road route.

Where roadworks and lane restrictions are expected
Beyond full closures, drivers should watch for lane restrictions, Stop/Go systems and daytime traffic management at multiple locations. Key works are scheduled in:
- York Road, Dún Laoghaire
- Ballybrack Village
- Churchtown Road Upper
- Ballybetagh Road
- Killiney Avenue
- Frascati Park, Blackrock
Additional short-duration works are also expected in Stillorgan, Shankill, Dundrum, Dalkey and Deansgrange. Most operations are planned between 10am and 4pm to reduce pressure on rush-hour traffic, although some congestion should still be expected.
Dundrum development work adds to local traffic pressure
Enabling works have now started on Dún Brí, the new housing development on the former Central Mental Hospital site in Dundrum. The project is expected to deliver hundreds of affordable and social homes, but in the near term it will bring increased construction traffic and occasional traffic management measures in the surrounding area.
Most construction activity is being kept within the site boundary, with road cleaning and safety controls planned as works continue. Standard working hours are Monday to Friday from 7am to 7pm, and Saturdays from 8am to 2pm.

Active travel schemes continue across the county
This week’s Dublin news also includes continued progress on active travel and school safety projects. Ongoing works remain in place on the Dún Laoghaire Central Active Travel Scheme, particularly around Glenageary Road Upper and Mounttown Road, where junction controls may slow movement. The Dodder Greenway Ely’s Arch project is also ongoing, with intermittent traffic impacts.
Safe Routes to School works continue in Dundrum, Blackrock and other areas, with pedestrian access being maintained wherever possible.
What drivers should do before setting out
- Allow extra time for local and regional journeys.
- Check diversion signage, especially near Dundrum, Blackrock and Kilternan.
- Slow down through managed works zones.
- Expect daytime delays on secondary roads as resurfacing and footpath works continue.
For anyone commuting, making deliveries or navigating school and residential areas, this Dublin news update is a reminder that planning ahead matters. With closures, resurfacing and development works all active at once, a little preparation can make travel across south Dublin far smoother this week.
