New works and major projects underway
Fresh works beginning this week include resurfacing in Smyth’s Villas and York Road in Dún Laoghaire, reinstatement works in Ashlawn Park, Ballybrack, and drainage clearance at Shanganagh Cliffs and Cherrywood Park in Shankill.
Meanwhile, larger infrastructure schemes continue across the county, including:
- Footpath works on Granville Road, Kilbogget
- Surfacing at Puck’s Castle Lane and Murphy’s Lane
- Road surfacing between Marino Avenue West and Station Road, Killiney
- Traffic calming and footpath improvements on Churchtown Road Upper
- Foul main installation works at Cherrywood Campus
- Lane restrictions on Dundrum Road
Most of these locations are operating under Stop/Go systems or temporary traffic management, so drivers should allow extra time where possible.
Pedestrian safety and active travel improvements
A separate public consultation notice has been issued for a proposed signalised pedestrian crossing at the N11 Cornelscourt Junction. The plan includes signal upgrades, tactile paving, kerb improvements, road markings and signage designed to improve safety, accessibility and connections to public transport.
There are also continued Active Travel and Safe Routes to School works at several school and community locations, including Dodder Greenway, Holy Cross National School in Dundrum, Carysfort National School, Holy Family National School and The Harold School.
