Weekend traffic: Souligny Ave. closed eastbound

No new major highway disruptions are planned this long weekend, but here are some other things to look out for:

Souligny Ave.: Closed eastbound between Dickson St. and Honoré-Beaugrand St. from 11 p.m. Thursday to 5 a.m. Tuesday, including the ramps toward Highway 25 and the bridge over it. The highway remains open and can be accessed by Hochelaga or Notre-Dame Sts.

Viger Ave.: Lane closings between the Route 136 entrance and Wolfe St. to replace a water main. Two lanes will be open during the morning rush hour and one lane during other times.

The Réseau express métropolitain will begin serving the full Deux-Montagnes branch after 9 p.m. starting Monday. Final departures from Deux-Montagnes will be at 12:48 a.m. on Saturday nights and 12:29 a.m. on other nights. Service between Côte-de-Liesse and Deux-Montagnes has closed early since the branch launched to facilitate testing of the Anse-à-l’Orme branch, set to open this spring.

But there’s also bad news next week: The REM will close early and/or open late the two weekends after this one — first departures at 7:30 a.m. on April 11, 12, 18 and 19, and last trains at 10:13 p.m. from Deux-Montagnes and 10:40 p.m. from Brossard on April 17 and 18.

Next weekend, from April 10 to 13, the Ville-Marie and Viger tunnels will be completely closed to demolish part of the St-Urbain St. overpass. The last open exit eastbound will be Robert-Bourassa Blvd./de la Montagne St., and the first open exit westbound will be Lucien-L’Allier St.

• REM: Trains leaving Brossard have two alternating destinations — Deux-Montagnes and Bois-Franc. The latter trains will continue to Anse-à-l’Orme station when that branch opens later this spring. Display boards at the stations indicate the destinations of each train (those that say they go to Anse-à-l’Orme will disembark all passengers at Bois-Franc, who can take the next train toward Deux-Montagnes to continue down the line).
• Highway 10: Eastbound Exit 3 for Carrie-Derick St. is permanently closed as part of the rebuilding of the Bonaventure.
• 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 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-10 a.m. weekdays and toward Vaudreuil-Dorion from noon to 10 p.m. weekdays and all weekends and holidays).
• Route 138: In LaSalle, one of two lanes is closed in each direction at Clément St. until April 18.
• 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 northbound-only between Ste-Catherine St. and de Maisonneuve Blvd., with only one lane open at Ste-Catherine.
• 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 Atataken and Ontario Sts. STM buses 30 and 50 have been cut short to avoid the area, and express bus 427 has been suspended, with additional departures added to the 27 bus on St-Joseph Blvd. in the Plateau.

• 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.
• 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.
• De Lorimier Ave. (Ville-Marie): Closed northbound between René-Lévesque Blvd. and de Maisonneuve Blvd., from Mondays to Wednesdays from 7 a.m. to 7 p.m., and Thursdays from 7 a.m. to 6 p.m., until the end of April, for water infrastructure work by the City of Montreal.
• De Châteaubriand Ave. (Rosemont—La Petite-Patrie): Closed until the end of June for sewer work between Jean-Talon St. and Bélanger St.
