There will also be disruptions on Route 132 at the Champlain Bridge.
Access to downtown will be more complicated than usual this weekend, as the Ville-Marie Expressway (Route 136) will be completely closed eastbound for the entire weekend.
Route 136
Route 132
The ramp from Route 132/Highway 20 westbound toward the bridge will be closed during this time, as this is the overpass being repaired. Detours will be marked. Traffic is recommended to take Highway 30 to get to and from the bridge, or use public transit.
Highway 40
Continuing disruptions
- Métro: The discovery of a structural issue has forced the closure of the St-Michel station on the Blue Line until further notice. A bus, Line 809, shuttles users between Jean-Talon and d’Iberville stations during the métro’s opening hours.
- Highway 10: The access to Highway 10 West (Bonaventure Expressway) from Nuns’ Island is closed until the end of November.

- Pie-IX Blvd.: Work to extend the SRB Pie-IX south means only one lane is open in each direction between Pierre-de-Coubertin Ave. and Notre-Dame St. Cross-streets between de Rouen and Ste-Catherine Sts. are closed at Pie-IX.
- St-Urbain St.: The overpass over the Ville-Marie Expressway is closed for a long renovation, until the end of 2026. Pedestrian access is maintained.
