19-06-2025

With Grand Prix weekend behind us, work resumes on highways around Montreal, and the Réseau express métropolitain returns to being closed on weekends. Here are trouble spots to watch out for:
Highway 19
The highway, including the Papineau-Leblanc Bridge connecting Montreal and Laval, will be completely closed in both directions from 10 p.m. Friday to 5 a.m. Monday — northbound between Henri-Bourassa Blvd. and de la Concorde Blvd., and southbound from Highway 440 to Henri-Bourassa Blvd. Access to St-Martin Blvd. will be maintained via the service road.
From Monday until the end of 2026, two lanes will be open on the bridge in each direction, with partial or complete closures on some nights.
Île-aux-Tourtes Bridge
Highway 40 between Montreal Island and Vaudreuil-Dorion will have only one lane open westbound from 7 p.m. Saturday to 10 a.m. Sunday.
Mercier Bridge
The upstream span of the bridge will be closed from 11 p.m. Friday to 5 a.m. Sunday, requiring traffic to share the other span, with one lane in each direction. The entrance from Airlie St. and the reserved bus lane will be closed during this time. In case of bad weather, the work will take place from 11 p.m. Saturday to 5 a.m. Monday.
La Fontaine Tunnel
The tunnel will be closed in both directions from 11 p.m. Friday to 8 a.m. Saturday, from Souligny Ave. to Île Charron, for work on electrical and communication systems in the tunnel. Souligny Ave. over the highway will also be closed during this time.
Highway 30
In Les Cèdres, one lane will be open westbound Saturday and Sunday from 6 a.m. to 8 p.m.
Mont-Tremblant
The Ironman 70.3 Mont-Tremblant run will mean closing part of Route 117 near the city on Sunday from 6 a.m. to 3 p.m. Traffic will share one side of the highway between Mont-Tremblant and Labelle. Parts of Montée Ryan and Duplessis Rd. will also be closed that day.
Montreal streets
Côte-de-Liesse Rd.: Two of three lanes will be closed eastbound before Rockland Rd., from Tuesday until November. Ramps to Acadie Blvd. south from Highway 15 and Côte-de-Liesse Rd. will be closed.
René-Lévesque Blvd.: Downtown, two of four lanes will be closed westbound between Wolfe and Atateken Sts. from 7 a.m. Saturday to 7 p.m. Sunday.
Jean-Milot St.: In LaSalle, the street will be completely closed between Lafleur Ave. and Newman Blvd. from Monday to July 11.
Continuing disruptions
REM: The Réseau express métropolitain remains closed on weekends and ends service at 8:20 p.m. weekdays until July 4, when it closes completely for six weeks. Replacement shuttle buses will run between the stations when the REM is not operating, except from 1:30 a.m. to 5:30 a.m.
Highway 10: A westbound lane on the Bonaventure Expressway is closed between the Victoria Bridge and Wellington St. until December. On the Clément Bridge connecting Montreal with Nuns' Island, traffic runs contraflow with one lane in each direction until December.
Highway 20/Route 132: In St-Lambert, repaving work on a section of the eastbound highway between the Champlain Bridge and Notre-Dame Ave. requires it to close from 8 p.m. to 5 a.m. until the end of July.
Highway 40: The Île-aux-Tourtes Bridge between Vaudreuil-Dorion and Montreal Island is down to two lanes in each direction.
Ste-Catherine St.: The street is closed to traffic between Stanley St. and McGill College Ave. for work on major renovations through summer.
Jean-Talon St.: Work on building the Blue Line métro extension will force parts of Jean-Talon St. to be closed. Affected buses (in particular 141 and 372) are detoured onto Bélanger and Everett Sts. to avoid those areas.
St-Jacques St.: Work on underground infrastructure has closed the street between St-Philippe St. and Ste-Marguerite St. until June 30.
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. Ste-Catherine St. and Hochelaga St. remain open through Pie-IX, but other cross streets are closed west of 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.
