Expect road closures and detours in Montreal this long weekend

You may have many things to be thankful for this weekend but Montreal’s major roadways will not be one of them. Transports Quebec has warned against heavy road closures, congestion and detours from Friday to Tuesday on the Turcot Interchange and the Champlain and Mercier Bridge.

We’d recommend getting your Thanksgiving supplies well in advance. If you are planning on getting off the island (or coming in), give yourself plenty of time to spare.

The only thing we’ll be giving to Montreal roads this weekend is aggression.

Turcot Interchange

On the Turcot, the exit from Highway 20 (east) to Highway 15 (north) and the Décarie Expressway will be closed from Friday at 11:59 pm until Tuesday at 5 am.

Exit 63 towards the Mercier Bridge will also be closed from Friday at 11:59 pm to Tuesday at 5 am.

Champlain Bridge

Highway 15 (north) will be reduced from three lanes to one from Nun’s Island and Boulevard Gaétan-Laberge in Verdun from Friday at 10 pm to Tuesday at 5 am.

The downtown exit for Montreal off Highway 15 (north) will also be closed from Friday at 10 pm to Tuesday at 5 am.

Highway 15 will be closed completely between Exit 63 and the 20 West as well as the rue Sherbrooke entrance ramp.

Mercier Bridge

The Mercier Bridge will reduce to one lane in each direction from Friday at 10 pm until Tuesday at 5 am.
