Because of the Formula One Canadian Grand Prix race, no major roadwork events are planned this weekend in Montreal.

However, to facilitate traffic toward the event, the schedule for the Victoria Bridge is changing.

On Friday, traffic will be only toward Montreal as usual from 5 a.m. to 9 a.m., but then only toward the South Shore from 9 a.m. to 10:30 a.m. From 10:30 p.m. and for the rest of the day it will have one lane in each direction, including afternoon rush hour.

On Saturday, both lanes will be toward the South Shore from 7 a.m. to 10:30 a.m., and one lane each way after 10:30 a.m.

On Sunday, both lanes will be toward the South Shore from 7 a.m. to 11:30 a.m., then one lane each way after 11:30 a.m.

Those attending the race are asked to use public transit. The STM is offering a special “weekend GP” pass at Opus card stations and through the Chrono app that allows unlimited travel in Montreal from 5 a.m. Friday through 5 a.m. Monday, for $20.50.

Highway 30

In Vaudreuil-Dorion, the eastbound exit to and entrance from Route 340 is closed from 8 p.m. Friday to 5 a.m. Monday. Cité-des-Jeunes Blvd. is partially closed until November over the highway.

River shuttles

Montreal’s transit river shuttles return Friday. One between Mercier and Boucherville is free, and the others cost $6 or are no extra charge for those with weekly or monthly passes.

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 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).

Highway 520: Work on the overpass over 43rd Ave. is closing the service road between Riddle Ave. and 46th Ave. until about June 10. Work will also close 43rd Ave. and several other streets in the sector.

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 buses 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 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.

De Chateaubriand Ave. (Rosemont—La Petite-Patrie): Closed until the end of June for sewer work between Jean-Talon and Bélanger Sts.
