Trucks will be banned from taking the Mercier towards Montreal during morning rush hours and won’t be able to travel southbound during the afternoon rush hour.

During the bridge’s first weekend of closure (June 26 to 28), free passes will be given out for the Exo Bus and Candiac’s Exo4 Line to ease mobility.


Rush hour will be extended on the Victoria Bridge to alleviate the island’s congestion during the Mercier’s construction.

Two lanes on the Victoria will be open from 5 am to 10 am (towards Montreal) and from 2 pm to 8 pm (toward the South Shore).

Trucks however, will be prohibited from using the Victoria Bridge during the extended two-lane rush hour times.
