Motorists across south Dublin should expect a week of diversions, temporary speed limits and localised delays as several transport and resurfacing projects continue. This Dublin news update covers the main road closures, lane restrictions and active travel works affecting journeys in Dún Laoghaire-Rathdown from Saturday 27 June to Friday 3 July 2026.
Dublin news: Main traffic changes drivers should know this week
The biggest impact this week comes from ongoing speed restrictions and road closures linked to resurfacing, school safety upgrades and major infrastructure works. For commuters, residents and local Dublin business operators, planning ahead will be essential.
Temporary speed limits in place
M11 northbound: A temporary 60km/h limit applies from the county boundary near Junction 7 to Junction 5 until 17 July while resurfacing works continue.
Wyattville Link Road westbound: A 50km/h speed limit remains in force from Cherrywood Avenue to the Cherrywood M50 southbound slip road until 30 November 2026, or until works are finished, to support the underpass project.
Road closures this week
Kilmacud Road Upper, Dundrum: closed until Saturday 27 June between Dundrum Garda Station and Dundrum College for resurfacing under 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 linked to school route safety improvements.

Where additional roadworks are happening
Beyond full closures, drivers should also expect stop-go systems, temporary lane restrictions and reduced movement in several neighbourhoods. Current works are affecting:
York Road, Dún Laoghaire
Ballybrack Village
Churchtown Road Upper
Ballybetagh Road
Killiney Avenue
Frascati Park, Blackrock
Short-duration works are also expected in Stillorgan, Shankill, Dundrum, Dalkey and Deansgrange. Most crews are scheduled between 10am and 4pm to reduce rush-hour disruption, though some delays are still likely.
Dundrum development and active travel projects continue
A separate part of this Dublin news update involves construction activity at Dún Brí, the major housing development on the former Central Mental Hospital site in Dundrum. Early enabling works including demolition, utility setup and site preparation are now under way.
While most activity is staying within the site boundary, nearby residents should expect construction traffic to increase as the project progresses. The development is set to deliver hundreds of affordable and social homes, making it an important project for the area and for wider Dublin business and community growth.
Active travel schemes are also advancing, including works on Glenageary Road Upper, Mounttown Road and the Dodder Greenway connection at Ely’s Arch. Safe Routes to School projects are continuing in Dundrum, Blackrock and other locations, with pedestrian access being maintained throughout.
