Montreal's Highway 40 Overpass Repairs to Cause Traffic Delays Starting April 20
The Ministry of Transport and Sustainable Mobility has announced a major infrastructure project that will impact commuters in Montreal. A multi-year, $8.7-million repair initiative for the Lacordaire Boulevard overpass above Highway 40 is set to commence on April 20, 2026. This extensive work will result in recurring lane closures on both Boulevard Lacordaire and Highway 40, leading to anticipated traffic delays and disruptions for drivers in the area.
Project Details and Timeline
The repair project, which involves critical structural enhancements to the overpass, is expected to span several years. Starting April 20, 2026, at 8:46 PM EDT, construction activities will begin, with lane closures implemented periodically to facilitate the work. The Ministry has emphasized that these closures are necessary to ensure the safety and longevity of the overpass, which serves as a vital link in Montreal's transportation network.
Impact on Traffic and Commuters
Drivers should prepare for significant traffic delays as the lane closures on Boulevard Lacordaire and Highway 40 will reduce capacity during peak hours. The Ministry advises motorists to seek alternative routes or adjust their travel schedules to avoid congestion. Public notifications will be issued regularly to update the community on closure schedules and progress.
This project underscores the ongoing efforts to maintain and improve Montreal's aging infrastructure, with a focus on sustainable mobility and safety. Residents and commuters are encouraged to stay informed through official channels to minimize inconvenience during the construction period.
