More weekend closures are on the way for Montreal drivers, with multiple construction projects expected to disrupt traffic across the region from Friday night through Monday morning.
According to Quebec’s transport ministry, key routes including the Ville-Marie Tunnel, Honoré-Mercier Bridge, and Louis-Hippolyte-La Fontaine Tunnel will see full or partial closures as crews carry out scheduled work.
So, if you’ve got plans to hit the road, here are the areas that could cause frustration:

From Saturday, May 24 at 11 p.m. to Monday, May 26 at 5 a.m., there will be contraflow traffic on the upstream span (toward the South Shore), leaving just one lane open in each direction.
