Traffic obstruction on Notre-Dame Street West at the South Viaduct

Nature of the work

Rehabilitation work is continuing under the South Viaduct railway tracks in preparation for the arrival of the REM.

Impacts and mitigation measures

A major traffic obstruction is planned from Friday, October 9 at 11 a.m. to Tueday, October 13 at 5 a.m. as part of this work:

• Traffic will be completely closed on the section of Notre-Dame Street West running between Robert-Bourassa Boulevard and De l’Inspecteur Street.
• Adequate signage will be present to indicate the proposed eastbound detour route. Police officers will also be on hand to manage traffic.
• The sidewalks will remain closed under the South Viaduct. The current detour route, via Saint-Maurice Street, will remain in effect.
• This work will generate noise. Environmental experts will monitor noise to ensure project criteria are met. Additional mitigation measures may be implemented if necessary.
