Proposed pedestrian crossing at Cornelscourt

The Council has given notice of its intention to provide a signalised pedestrian crossing at the N11 Cornelscourt signalised junction.

The works include modifications to the existing traffic signals, road markings, footpaths, kerbing, tactile paving and signage. The crossing aims to improve accessibility and safety for pedestrians and cyclists, improve connectivity to nearby bus stops, and support the safe movement of vulnerable road users through the junction. Drawings and particulars can be viewed at dlrcoco.ie/traffic-management/traffic-news.

Please allow extra time when travelling through affected areas and follow temporary signs and traffic management instructions.
