Drivers across south county Dublin are being urged to check routes before setting out, with a busy week of closures, lane restrictions and infrastructure works affecting several key roads. This latest Dublin news update covers the main traffic changes in Dún Laoghaire-Rathdown for 25 to 31 July 2026, including major diversions, active travel works and public consultation notices.
The biggest long-running disruption remains on the Wyattville Link Road, where a temporary 50km/h speed limit continues on the westbound section between Cherrywood Avenue and the Cherrywood M50 southbound slip road. The measure is tied to underpass construction linked to the Beckett Link Road Project and is expected to stay in place until late November unless works finish sooner.

Major infrastructure works likely to cause delays
Some of the most significant delays are linked to longer-term projects already under way across the county. Brides Glen Road in Shankill remains closed for watermain installation, while part of the Enniskerry Road in Kilternan continues under restricted access due to realignment and carriageway upgrades.
Motorists should also watch for ongoing impacts at:
- Wyattville Link Road westbound: closed between Cherrywood Avenue and the Cherrywood M50 on-slip.
- M50 Junction 14 Link Road Scheme: overnight and daytime lane closures on the Leopardstown Road roundabout.
- Churchtown Road Upper: stop/go traffic management remains in place for road and footpath improvements.
- Dundrum Road: single-lane restrictions continue during boundary wall works.
These schemes are part of wider transport, drainage and safety upgrades that may shape future commuting conditions for residents, students planning to Study in ireland, and workers considering how local mobility affects daily travel.

School travel projects and consultation updates
Safe Routes to School works are continuing at Holy Cross NS, Carysfort National School, Holy Family National School and The Harold School. Most locations are nearing completion, with remaining snagging, paving, drainage and signal works scheduled during school holidays to reduce disruption.
Meanwhile, the council is also seeking public feedback on a proposed signalised pedestrian crossing at the N11 Cornelscourt junction. The plan is intended to improve safety, bus stop access and walking and cycling links in the area. Submissions are open until 3 August 2026.
For anyone tracking weekly Dublin news, the key takeaway is simple: expect delays, check diversions in advance and pay close attention to local signage, especially around Cherrywood, Dundrum, Shankill and Killiney. With roadworks spread across multiple corridors, staying updated on Dublin news can make commuting far less stressful.
