Dublin Traffic: Roadworks Update for Dún Laoghaire-Rathdown This Week

Drivers across south Dublin are being urged to check routes before setting off, with a fresh round of traffic restrictions now affecting Dún Laoghaire-Rathdown. This Dublin news update covers the main road closures, reduced speed zones and ongoing works likely to impact commutes between Saturday 20 June and Friday 26 June 2026.

Local authorities have warned that resurfacing, maintenance, utility activity and active travel projects will cause delays in several busy areas. For residents, commuters and visitors moving through the county, planning ahead will be essential this week.

Dublin news: Main traffic changes this week

Several temporary traffic measures are now in force across the county, including speed restrictions and full road closures.

Temporary speed limits in effect

• M11 northbound: A temporary 60km/h limit applies from the county boundary near Junction 7 to Junction 5 from 22 June to 17 July 2026 while resurfacing is carried out.

• Wyattville Link Road westbound: A 50km/h speed restriction remains between Cherrywood Avenue and the Cherrywood M50 southbound slip road. This measure is expected to stay in place until 30 November 2026, subject to construction progress on the underpass project.

Current road closures to watch

The following routes are among the most significant disruptions this week:

• Kilmacud Road Upper, Dundrum: closed from 22 to 26 June for resurfacing linked to the Safe Routes to School scheme

• Hillcrest Road, Sandyford: partial closure on 24 June for maintenance and cleaning

• Sutton’s Lane, Ballycorus: closed on the afternoon of 24 June for cleaning works

• Enniskerry Road (R117), Kilternan: closed until 28 August for major road upgrades

• Knapton Road, Dún Laoghaire: closed until 17 July as part of the Active Travel Scheme

• Wyattville Link Road westbound: closure remains in place until 30 November with alternative traffic layouts operating

Where additional delays are expected

Beyond the closures, traffic management systems and lane restrictions are also in place in a number of areas. These include Ballybrack, Blackrock, Sandyford, Bray Road, Dalkey, Stillorgan and Deansgrange.

Most of these works are happening during daytime hours and are being managed with Stop/Go systems or temporary lane narrowing. That means motorists may face short but frequent delays, especially on local approaches and at junctions.

Active travel projects continuing

Several transport improvement schemes are also progressing:

• Dún Laoghaire Central Active Travel Scheme, including works on Glenageary Road Upper and Mounttown Road

• Dodder Greenway works near Ely’s Arch

• Safe Routes to School projects at multiple locations across the county

In most cases, crews are operating between 10am and 4pm to reduce rush-hour disruption, while pedestrian access is being maintained.

What motorists should do now

Anyone travelling through Dún Laoghaire-Rathdown this week should:

• Allow extra time for journeys

• Follow marked diversion routes

• Drive carefully through managed traffic zones

• Check for overnight or daytime restrictions before departure

While this update is rooted in Dublin news, it also matters to commuters, families and newcomers adjusting to daily movement around the capital. For those who study in Ireland or plan to work in Ireland, local transport conditions can have a direct impact on routines and access.

Overall, this week’s Dublin news points to heavier disruption across key roads in Dún Laoghaire-Rathdown, particularly where resurfacing, school safety upgrades and active travel works overlap. The clearest takeaway is simple: check your route, expect delays and use extra caution in affected areas.
