Public Transit Alternatives

The STM is adding extra bus service on major routes and increasing Metro frequency during the closures. Commuters are encouraged to use the Metro, particularly the Orange and Green lines, to bypass road construction.

For real-time updates, drivers can check Quebec's road information portal or use navigation apps. Authorities remind everyone to obey construction signs and reduce speed in work zones for safety.
