For drivers, summer 2022 will be marked by noise, dust, huffs, puffs, and likely more than a little screaming at no one in particular. Mobilité Montréal has released a long (long, long, long) list of Montreal highway construction projects that will affect traffic in the months ahead.

Believe it or not, the compilation below is only a partial list, including major projects on highways, bridges and thoroughfares on Montreal Island only. A complete list, including construction on the local street network and off-island highway stretches, as well as timelines, is available online.
