Obstructions can impede traffic on certain axes of the freeway network, particularly in Montreal and Brossard, on weekends.
Eastbound Route 136 will be completely closed between the Turcot interchange and the entrances to Notre-Dame and de la Cathédrale streets from midnight Saturday to 5 a.m. Monday.
At the Saint-Pierre interchange, Mobility Montreal plans to completely close the Westbound on-ramp from Route 138 to Autoroute 20 for the same period.
In Brossard, Route 132 under the Samuel De Champlain Bridge will be completely closed in both directions from Friday 11 p.m. to Monday 5 a.m.
According to Mobility Montreal, this closure is due to the dismantling work on the old Champlain Bridge, which also includes the closure of Marie Victorin Boulevard.
The westbound Highway 40 service road will be closed between Devonshire Road and Alexis-Nihon Boulevard from 10 p.m. Friday to 5 a.m. Monday.
In the La Prairie sector, 2 out of 3 lanes will be closed on Southbound Autoroute 15 between Matte and Taschenreau Boulevards from Friday 7:00 p.m. to Monday 5:00 a.m.
In addition, the works will force the closure of 2 out of 3 lanes in both directions on Highway 15 every night Sunday through Thursday through mid-October.
