New phase of Ste. Catherine Street West roadwork to affect access around the Sir George Williams Campus

A new phase of the City of Montreal’s Ste. Catherine Street West project began Monday, March 30, bringing road closures and traffic changes to the area surrounding Concordia’s Sir George Williams Campus.

Sections of Ste. Catherine Street West between Saint-Mathieu and Crescent streets are closed until mid-May.

Impacts on nearby streets

Bishop Street (until mid-May)

• Intersection closed at Ste. Catherine Street West.
• Two-way local traffic maintained north toward De Maisonneuve Boulevard West and south toward René-Lévesque Boulevard.

Guy Street (until the end of summer)

• Intersection closed at Ste. Catherine Street West.
• Two-way local traffic maintained north toward De Maisonneuve Boulevard West and south toward René-Lévesque Boulevard.

Pierce Street (until mid-November)

• Two-way local traffic maintained between the work zone and De Maisonneuve Boulevard West.

Additional closures and changes may occur as work progresses through the year.

Pedestrian access to Concordia buildings will be maintained at all times, with detours clearly marked. Public transit service will continue, although some stops and schedules may be adjusted.

Work is scheduled Monday to Friday from 6 a.m. to 3 p.m. While most activities will take place during these hours, work may occur evenings or weekends as needed to minimize disruptions, particularly during work on water and sewer lines and near building entrances.
