As of Friday night, half of the Mercier bridge will close to road traffic for two months. 

The provincially-owned portion of the bridge toward Kahawake and Chateauguay is scheduled to close precisely at 10 p.m. on Friday June 22.

Construction workers will then take over the span and following a two-month blitz, they wil reopen the bridge on August 20.

Commuters will not be stranded, but their travel will be restricted.

Over the summer drivers will be diverted to the other half of the bridge, which will have one lane operating in each direction for June, July, and August.

During this time the Airlie St. entrance to the Mercier Bridge will also be off-limits, with drivers having to detour via Lafleur Avenue and Clement St. to access the bridge.

Airlie will also have one reserved lane for buses running daily between 7 a.m. and 7 p.m. 

Meanwhile, over the summer, there will be several weekends when the bridge will close entirely, and Lasalle Blvd. will also be closed for construction.
