Drivers, cyclists and pedestrians travelling through south Dublin should plan ahead this week as road closures, diversions and temporary traffic controls affect several areas. This Dublin news update covers the main works scheduled across Dún Laoghaire-Rathdown from Saturday, 3 October, to Friday, 9 October 2026.
Key traffic changes across south Dublin
Dún Laoghaire-Rathdown County Council advises road users to allow additional journey time and follow temporary signs. The information was current at 4pm on Thursday, 1 October, although emergency works may be introduced without advance notice.
- Wyattville Link Road: A temporary 50 km/h limit remains on the westbound section between Cherrywood Avenue and the Cherrywood M50 southbound slip road. The restriction is linked to construction of the Wyattville Link Road underpass and is expected to continue until 30 November, or until works finish.
- Brides Glen Road, Shankill: The road remains closed between Rathmichael Road and Mullinastill Road while a large-diameter watermain is installed. The closure is scheduled to remain until 28 November.
- Mounttown Road Lower: A temporary northbound-only system continues between Kill Avenue and York Road as part of the Dún Laoghaire Central Active Travel Scheme. Southbound motorists should use signed diversions.
- Silchester Road, Glenageary: A section near Silchester Crescent will close from 10am to 4pm on Friday, 9 October, for permanent reinstatement works. Local and pedestrian access will be maintained.
