Drivers heading into Montreal this weekend should note that construction projects will leave some routes less than fluid, and the Santa Claus Parade on Saturday will result in backed-up traffic downtown. Santa Claus Parade Motorists are advised to avoid the entire area for the morning as crowds begin forming at least an hour before the parade. Honore-Mercier Bridge (R-138) De l’Acier/Highway 30 (Brossard) Saint-Jean-Baptiste Boulevard/R-138 (Châteauguay) All work may be cancelled due to weather or operational constraints.
