Drivers in south Dublin are being urged to leave extra time for journeys as fresh traffic measures, temporary closures and infrastructure works affect key routes this week. This latest Dublin news update covers the main disruptions across Dún Laoghaire-Rathdown from 25 to 31 July 2026, with several schemes also stretching into August and beyond.
The biggest long-running change 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 restriction is linked to underpass construction for the Beckett Link Road Project and is expected to stay in place until late November unless works finish sooner.
Dublin news: key road closures and live traffic changes
A number of approved and planned works are set to affect local access in Blackrock, Dundrum, Killiney, Cabinteely and surrounding areas. Motorists, cyclists and residents should watch for diversions, stop/go systems and temporary one-way arrangements.
- Brennanstown Road: closed from 4 to 24 August for surface water drainage works.
- Mounttown Road Lower: proposed southbound one-way restriction from 4 August to 30 October as part of the active travel scheme in Dún Laoghaire.
- Dodder Road Lower: approved closure from 10 August for about one week for cycle scheme improvements.
- R117 Dundrum Wood: overnight closure on 26 July for building-related mechanical works near Dundrum Town Centre.
- Old Bray Road, Cabinteely: water connection works from 29 to 31 July, with traffic signals temporarily out of operation.
Elsewhere, maintenance and resurfacing activity continues on Puck’s Castle Lane, Murphy’s Lane, Marino Avenue East, Station Road and Granville Road. In Cherrywood, foul main installation works are also expected to cause delays through late August.

Longer-term schemes likely to impact commuters
Several major projects will continue to shape traffic patterns well beyond this week. Brides Glen Road in Shankill remains closed until 26 September for a major watermain installation, while partial closure arrangements stay in place on the Enniskerry Road in Kilternan for road realignment and carriageway upgrades.
The westbound Wyattville Link Road closure also remains a major pinch point, with alternative traffic management operating via M50 slip roads. In Glenamuck and Carrickmines, road access restrictions tied to district road upgrades and future bus gate measures are set to change how through traffic moves in the area.
These projects reflect broader transport and planning developments that matter not only to commuters but also to Dublin business activity, delivery routes and local mobility.
School travel and active travel works
Safe Routes to School projects are advancing at Holy Cross NS, Carysfort National School, Holy Family National School and The Harold School. Most of the heaviest surfacing work has been completed at some sites, but snagging, drainage, paving and signalling works are still ongoing in places.
At the same time, the Dodder Greenway and related cycling infrastructure works continue near Orwell Road and Braemor Park, with further traffic impacts expected in early August.

Public consultation and what road users should do next
A public consultation is now open on a proposed signalised pedestrian crossing at the N11 Cornelscourt junction, aimed at improving safety, accessibility and links to nearby bus stops. Submissions can be sent to Dún Laoghaire-Rathdown County Council by 3 August 2026.
For now, the clear takeaway from this week’s Dublin news is simple: check routes before travelling, expect delays around active works, and allow extra time if commuting through Dún Laoghaire-Rathdown. With road upgrades, school safety works and major infrastructure projects all happening at once, staying informed will make journeys easier and safer.
