Commuters across south Dublin are being urged to check routes before setting out, with a fresh wave of temporary closures, lane restrictions and traffic controls affecting key roads in Dún Laoghaire-Rathdown. For anyone following Dublin news this week, the latest update is especially important for drivers, cyclists, school-run families and local residents planning trips between 18 and 24 July 2026.
The council’s latest transport notice highlights both short-term disruptions and longer-running infrastructure projects, including works tied to active travel, resurfacing, drainage, gas upgrades and junction improvements.
Dublin news: key traffic changes drivers should know
One of the most notable ongoing measures remains on the westbound Wyattville Link Road, where a temporary 50km/h speed limit is still in place between Cherrywood Avenue and the southbound M50 slip. The restriction supports underpass construction linked to the Beckett Link Road Project and is expected to stay until late November unless works finish earlier.
Several active closures are also in place across the county, including:
- Puck’s Castle Lane and Murphy’s Lane, Rathmichael, for road maintenance until 9 August
- Torquay Road, Foxrock, for gas works until 26 July
- Marino Avenue East to Station Road laneway in Killiney for resurfacing
- Brock’s Lane, Dún Laoghaire, from 20 to 24 July
- Night works on Station Road, Killiney, for drainage, footpath and pedestrian crossing upgrades
Motorists should also prepare for lane restrictions at the Leopardstown Road roundabout as part of the M50 Junction 14 Link Road Scheme, where overnight closures and off-peak daytime traffic controls are expected through 31 July.
Longer-term works affecting local journeys
Some routes will remain disrupted well beyond this week. Brides Glen Road in Shankill, Enniskerry Road in Kilternan and parts of Wyattville Link Road continue to operate under traffic management due to major infrastructure activity. On Dundrum Road and Churchtown Road Upper, improvement works are also continuing, bringing intermittent delays.
These projects matter not just for daily travel but for the wider Dublin business environment, as smoother long-term transport links can improve access to retail centres, schools and employment hubs.

Active travel projects and school-area upgrades continue
Beyond standard road repairs, the county is pushing ahead with walking, cycling and accessibility projects. The Dún Laoghaire Central Active Travel Scheme is due to affect Mounttown Road Lower and Glenageary Road Upper from early August into mid-October, with extra journey time likely.
Meanwhile, the Dodder Greenway – Ely’s Arch Project is progressing at the Orwell Road and Braemor Park junction, with additional phases due shortly at Dodder Road Lower.
School-focused safety works are also ongoing during the summer break. Among the locations seeing upgrades are:
- Holy Cross NS, Dundrum
- Carysfort National School
- Holy Family National School
- The Harold School
These schemes include surfacing, junction redesigns, accessibility improvements and temporary traffic signals aimed at creating safer routes for children and families.

What road users should expect next
Looking ahead, additional proposed closures are scheduled for August in Blackrock, Dún Laoghaire, Brennanstown and Rathfarnham. These include works on George’s Avenue, Green Road, Mounttown Road Lower and Dodder Road Lower, with some diversions and one-way systems planned.
There is also an open consultation on a proposed signalised pedestrian crossing at the N11 Cornelscourt junction, a move intended to improve safety and access for both walkers and cyclists.
For residents, commuters and visitors alike, staying on top of Dublin news like this can make a real difference to journey planning. The key takeaway is simple: expect delays, allow extra time, and watch for changing traffic management across Dún Laoghaire-Rathdown as roadworks continue through summer.
