Parking lots and cemetery accesses will remain open.
Continuing disruptions
Highway 10: Eastbound Exit 3 for Carrie-Derick St. is permanently closed as part of the rebuilding of the Bonaventure.
Highway 13: In Laval, the southbound lanes are closed for renovation work until the fall between Ste-Rose Blvd. and Highway 440. Southbound traffic is rerouted to the service road, and during the morning rush hour (4-11 a.m.), a contraflow lane will be open on the northbound side for southbound traffic. Additional lanes will be closed overnights during the summer.
Highway 15: Repaving work has begun on the Laurentian Autoroute between Highway 40 and the Médéric-Martin Bridge to Laval, which will involve overnight and weekend lane closings until the end of 2027.
Highway 19 (Papineau-Leblanc Bridge): Two lanes are open on the bridge between Montreal and Laval in each direction, with partial or complete closings on some nights until the end of 2026.
Highway 20 (Vaudreuil-Dorion): Work to renovate the intersection of Harwood Blvd. and Bellemare St. continues until August. The work involves partial and complete closings overnight between Route 342 and Ranger Ave., and narrow 3.2-metre lanes and a 40 km/h speed limit otherwise. Detours will be set up using Chicoine St.
Highway 40 (Île-aux-Tourtes Bridge): The bridge is down to five lanes — two toward Montreal and two toward Vaudreuil-Dorion, with a fifth lane alternating directions (toward Montreal from midnight to 10 a.m. weekdays and toward Vaudreuil-Dorion from noon to 10 p.m. weekdays and all weekends and holidays).
Route 340 (Vaudreuil-Dorion): Cité-des-Jeunes Blvd. is closed until the end of August between de la Gare Blvd. and Henry-Ford St. to construct a roundabout. The exit from Highway 30 west to Route 340 is also closed until August. The overpass of Route 340 over Highway 30 is partly closed until November.
Jean-Talon St.: Work on building the Blue Line métro extension means parts of Jean-Talon St. are closed. Affected buses (in particular 141, 188 and 372) are detoured onto Bélanger and Everett Sts. to avoid those areas, and a temporary shuttle bus (No. 814) has been established along Jean-Talon and Bélanger Sts.
Ste-Catherine St. (Ville-Marie): Major work on the street and underground infrastructure means it is closed between St-Mathieu and Mackay Sts., and between de la Montagne and Peel Sts. Crossing streets are also blocked. Guy St. is closed at Ste-Catherine St.
Berri St. (Ville-Marie): Major work at the Berri-UQAM métro station has resulted in Berri St. being closed between Ste-Catherine and Ontario Sts., and de Maisonneuve Blvd. being closed between St-Denis and St-Hubert Sts. until November 2027. Traffic is detoured via St-Hubert, Atateken, St-Urbain or Ontario Sts., or René-Lévesque Blvd., while cyclists are being diverted to Atateken and Ontario Sts. STM bus routes have been cut short to avoid the area. For more information, visit stm.info.
Pie-IX Blvd. (Mercier—Hochelaga-Maisonneuve): 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. Ste-Catherine St. is blocked at Pie-IX, so traffic is rerouted via Notre-Dame St. until the end of June.
St-Urbain St. (Ville-Marie): The overpass over the Ville-Marie Expressway is closed for a long renovation until the end of 2026. Pedestrian access is maintained.
O’Brien St. (St-Laurent): Closed at Henri-Bourassa Blvd. until September for water main work.
