Weekend traffic: REM closes early Friday, runs all night Saturday

Transit

Montreal’s métro system and Réseau express métropolitain will be open late Saturday night as the city celebrates the Nuit Blanche all-nighter. Métro service on all four lines will continue until two hours past their normal closing times (last trains leave Berri-UQAM at 3 a.m.), while the REM will run throughout the night.

Night buses will stick to their usual schedules.

On Friday, however, the REM will shut down early as part of planned work. The last trains will leave Deux-Montagnes and Brossard at 8:10 p.m.

Highway 40

The Charles-De Gaulle Bridge connecting Montreal and Terrebonne will be down to two lanes in each direction from 9:30 p.m. Friday to 4 a.m. Monday. Lanes will be 3.3 metres wide and a speed limit of 50 km/h will be imposed.

Continuing disruptions

  • 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).
  • 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.
  • Côte-Ste-Catherine St. (Outremont): Closed westbound between McEachran Ave. and Davaar Ave. until late March for emergency electrical work.
  • 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.
