Montreal-area motorists are facing a difficult weekend on the roads, with major closures planned on the Samuel-De Champlain Bridge and the Décarie Expressway at the same time.
The Samuel-De Champlain Bridge will be completely closed northbound toward Montreal from 11 p.m. Friday, Aug. 28, until 5 a.m. Monday, Aug. 31.
The closure is needed for road repair work. Highway 15 North will also be closed from Exit 6, and access from Route 132 to Highway 15 North will be blocked.

No northbound traffic will be able to access the bridge during the closure.
The recommended detour will take drivers along Route 132 East, Route 134, and across the Jacques-Cartier Bridge.
Motorists are being encouraged to avoid the area during busy periods and consider public transit or working from home where possible.
The Champlain Bridge closure will overlap with major work on the Décarie Expressway.
Northbound Highway 15 will be closed between Jean-Talon Street and the entrance from Paré Street from 10:30 p.m. Friday until 5 a.m. Monday. The entrance from Édouard-Montpetit Boulevard to northbound Highway 15 will also be closed.
The Décarie work involves repairs to beams supporting the Des Jockeys and Ferrier street overpasses.
For drivers, the timing means two major northbound routes into Montreal will be restricted during the same weekend.
Traffic normally using the Champlain Bridge could be pushed toward the Jacques-Cartier Bridge, while drivers looking for an alternative route through Montreal will also face restrictions on Décarie.
West Island motorists are also dealing with ongoing work farther west on Highway 40 and the Île-aux-Tourtes Bridge.
The long-term project involves maintenance and reconstruction of the Île-aux-Tourtes Bridge and rehabilitation work on Highway 40. Lane configurations continue to change as construction progresses, with drivers travelling between the West Island and Vaudreuil-Dorion facing regular restrictions.
Overnight Highway 40 closures are also part of the continuing work in the Senneville and Vaudreuil-Dorion area.
The Highway 40 and Île-aux-Tourtes work will continue to affect West Island traffic beyond the weekend.

The Île-aux-Tourtes project is expected to continue for several years. A new bridge is being built alongside the existing structure, with the new span expected to open in 2027.
Once completed, the new bridge is expected to provide three lanes in each direction.
For now, however, drivers are being asked to plan around the construction.
With the Champlain Bridge and Décarie both affected this weekend, motorists are advised to check traffic conditions before leaving, allow extra travel time and follow temporary detour signs.
Drivers heading between the South Shore, Montreal and the West Island should be prepared for delays and consider changing their travel times if possible.
The weekend closures are scheduled to end early Monday morning, but the Highway 40 and Île-aux-Tourtes work will continue to affect West Island traffic beyond the weekend.
