The Jacques Cartier Bridge will be closed in both directions for the next two nights, and be severely restricted for several days after that.
Crews will be installing light fixtures over the bridge deck as part of the ongoing work to illuminate the bridge for Montreal's 375th birthday celebrations.
The bridge will be closed in both directions from 11:30 p.m. Thursday until 4 a.m. the next morning, and again on Friday night as of midnight.
One lane in each direction will be available for Friday evening before the full closure takes place.
Only one lane each way will be open on Saturday from 4 a.m. until 10 a.m., and again from 11 p.m. Saturday until 11 a.m. Sunday, and from 10 p.m. Sunday until 5 a.m. Monday.
Turcot work
Route 136 toward downtown will be closed all weekend.
The eastbound ramp from Highway 20 through the Turcot shuts at 11:30 p.m. Friday, and the connection from Highway 15 South to Route 136 closes at midnight.
Both ramps, and Route 136, will reopen on Monday at 5 a.m.
Drivers are being told to take the Bonaventure instead, and not to try to get around on surface streets.
Only one lane on St. Antoine St. West will be open between Atwater Ave. and Bourget St. from 8 p.m. Friday until 5 a.m. Monday as crews work on the sewage system in the area.
During the same time St. Patrick St. will be closed between Cabot and De l'Eglise as crews erect support pillars for Highway 15.
