Road closures and expected congestion are slated for the Mercier Bridge in Greater Montreal this weekend, affecting travel on Saturday, July 17, 2026, and Sunday, July 18, 2026. Motorists are advised to anticipate delays as the bridge undergoes planned disruptions that will limit normal traffic flow.
The scheduled work on the Mercier Bridge will create reduced capacity on one of the city’s key crossing points over the St. Lawrence River. Drivers seeking to cross the bridge during the two‑day period should expect slower movement and possible backup on approach roads. The timing of the closures has been set for both Saturday and Sunday, covering the entire weekend.
These interruptions are part of a broader series of road disruptions planned across the Greater Montreal area for the upcoming weekend. Several other routes are also slated for maintenance or construction, contributing to a citywide pattern of reduced roadway availability. The coordinated effort aims to address infrastructure needs while minimizing long‑term impacts on commuters.
Commuters are encouraged to allow extra travel time and consider alternative routes where feasible. Public information channels will continue to provide updates on the status of the Mercier Bridge and related roadwork throughout the weekend. Motorists should remain attentive to signage and any temporary traffic control measures implemented to manage the flow of vehicles during the closures.
