Drivers facing Montreal and regional highway corridors this weekend confrontation severe closures from October 2 to October 5, 2026, as the Ministry of Transportation and Sustainable Mobility launches major pavement resurfacing and concrete slab repairs across Autoroute 15, Autoroute 40, Route 116, and Route 158.
Another weekend of patience arrives for motorists navigating the Montreal metropolitan network. Major disruptions are officially underway across key commuter arteries, running from Friday evening through Monday morning according to transportation officials. The work focuses heavily on infrastructure rehabilitation, including crucial concrete slab repairs and roadway resurfacing projects designed to maintain aging expressway foundations before winter sets in.
Northbound Autoroute 15 Closures Impact Laurentian Sector
The Laurentian sector of Autoroute 15 takes the brunt of the weekend work schedule. The Ministry of Transportation and Sustainable Mobility (MTMD) scheduled complete and partial shutdowns spanning multiple days.
Daytime drivers will find little relief. From Saturday at 7 a.m. to Sunday at 10 p.m., the right lane of northbound Autoroute 15 will remain closed between Autoroute 40 and Sauvé Street West to maintain a single lane of partial flow. Authorities caution that weather conditions or operational constraints could force schedule adjustments.
Construction Shuts Saint-Michel Ramp Onto Westbound Autoroute 40
East-west commuters along the Metropolitan Autoroute 40 corridor face parallel construction zones centered around Saint-Michel and Pie-IX. The entrance ramp leading from Saint-Michel Boulevard onto westbound Autoroute 40 is shut down completely from Friday, October 2, at 10 p.m. until Monday, October 5, at 5 a.m. for essential concrete slab repairs reported by local transit coverage.
Along the Crémazie Boulevard West service road, westbound traffic faces partial lane reductions. Between the 18th and 14th Avenues, two lanes remain open from Friday at 10:30 p.m. until Saturday at 8 a.m. Farther west, between the 8th and 1st Avenues, only a single lane stays open across the entire weekend window. 2nd Avenue beneath Autoroute 40 is closed in both directions for the duration of the weekend operations according to municipal reporting.
Regional Highway Restrictions Across Brossard, Saint-Bruno, and Mirabel
Beyond Montreal’s central boroughs, outlying suburban links carry their own substantial traffic management challenges through Monday morning.
- Autoroute 10 / Route 132 Interchange (Brossard): Exit 6 on eastbound A-10 features a partial reduction of one out of two lanes, affecting the ramp toward westbound R-132. Drivers must detour via the Varennes-bound eastern ramp and execute a U-turn at Simard Boulevard noted in the official release.
- Route 116 / Sir-Wilfrid-Laurier Boulevard (Saint-Bruno-de-Montarville): Two-way counterflow traffic operates on the westbound roadway between Seigneurial West and De Boucherville boulevards. This specific restriction forms part of a recurring weekend work pattern scheduled to continue through the end of November.
- Route 158 (Mirabel): The roadway experiences a total closure in both directions between Autoroute 15 and Saint-Simon Road, forcing drivers onto designated detours via Autoroute 50 and connecting links verified by regional dispatch notes.
Transportation authorities strongly advise all motorists heading out across the metropolitan region to consult digital transit tools ahead of time and build substantial buffer time into their weekend schedules to follow the marked detours safely.
