Montreal traffic is looking brutal this weekend thanks to 2 major road closures

If you’re in the Greater Montreal area, make sure to check your route before heading out this weekend. Two major road closures are scheduled from October 18 to 20, and the province’s transportation ministry says drivers should prepare for significant disruptions.

The affected Montreal roads are frequently busy, so take note of the following obstructions to avoid dreaded Montreal traffic and find suitable detours to keep your weekend plans intact.

Here are the two closures to keep an eye on from Friday, October 18 at 11:59 p.m. until Monday, October 21 at 5 a.m., based on the latest updates from the Mobilité Montréal website at the time of publication.
