Dublin Digest: Traffic Update: Road Closures and Delays Across Dún Laoghaire-Rathdown This Week

Drivers moving around south Dublin this week are being urged to check routes before setting off, as a fresh traffic update highlights closures, diversions and lane restrictions across Dún Laoghaire-Rathdown. For readers tracking Dublin news that affects daily commutes, school runs and local business movement, the latest changes point to another busy week on several key roads.

A temporary 50km/h limit remains in place on the westbound Wyattville Link Road between Cherrywood Avenue and the Cherrywood M50 southbound slip road. The reduced speed is tied to underpass construction linked to the Beckett Link Road Project and is expected to stay until late November 2026 unless works finish sooner.

Road closures and traffic changes in this Dublin news update

Several temporary closures are planned in the coming weeks, with Blackrock, Dún Laoghaire, Brennanstown and Rathfarnham among the affected areas. Motorists should also note a proposed one-way arrangement on Mounttown Road Lower from early August through late October, with northbound traffic maintained and southbound vehicles diverted as part of the Dún Laoghaire Central Active Travel Scheme.

Current closures drivers should watch

  • R117 Dundrum Wood, Dundrum: closed on the morning of 26 July
  • Puck’s Castle Lane and Murphy’s Lane, Rathmichael: closed until 9 August
  • Torquay Road, Foxrock: closed until 26 July for gas works
  • Laneway between Marino Avenue East and Station Road, Killiney: closed for resurfacing
  • Brock’s Lane, Dún Laoghaire: closed from 20 to 24 July
  • Station Road, Killiney: night works continuing until 26 July

Longer-running infrastructure projects also remain active on Brides Glen Road, Kellystown Road, Enniskerry Road and Wyattville Link Road, all of which may add time to local journeys.

Major works likely to affect Dublin business and commuters

Beyond road closures, lane restrictions are expected at the M50 Junction 14 Link Road Scheme, especially around the Leopardstown Road roundabout where overnight closures continue through the end of July. Crosthwaite Park, Churchtown Road Upper, Dundrum Road and Kellystown Road are also seeing active works ranging from traffic calming to surface improvements.

For people following Dublin business activity, these disruptions matter beyond private travel. Delivery schedules, local retail access and service calls can all be affected when traffic management measures are spread across multiple neighbourhoods at once.

Active travel and school route projects continue

The county is also progressing several walking and cycling schemes. Works remain underway on the Dún Laoghaire Central Active Travel Scheme and the Dodder Greenway Ely’s Arch Project, with more activity planned at key junctions in early August. Safe Routes to School improvements are also ongoing at Holy Cross NS, Carysfort National School, Holy Family National School and The Harold School.

These projects are designed to improve long-term safety and accessibility, even if they create short-term delays for people who live or work in ireland’s capital region.

Public consultation and what drivers should do next

Dún Laoghaire-Rathdown County Council is also seeking public feedback on a proposed signalised pedestrian crossing at the N11 Cornelscourt junction, with submissions open until 3 August 2026. The plan is aimed at improving safety and accessibility for pedestrians and cyclists.

The clearest takeaway from this Dublin news roundup is simple: allow extra travel time, especially in Blackrock, Dundrum, Killiney, Shankill and around the M50 link routes. With roadworks, school access schemes and larger infrastructure projects all happening together, advance planning will make journeys smoother and help residents stay ahead of changing traffic conditions.
