Two major exits in the Turcot Interchange will close for at least three months starting in late August.

The closures (see map below):
 - Ville-Marie east to Decarie Expressway north: Detour by continuing on Ville-Marie east to the Guy St. exit and double back via Ville-Marie west
 - Ville-Marie west to Decarie Expressway south to the Champlain Bridge: Detour by continuing on Ville-Marie west to the Angrignon Blvd. exit and double back via Ville-Marie east

During that time, workers will repair the concrete decks and repave the ramps. It's part of $3.7 billion being put into rebuilding the Turcot and neighbouring work for the next six years.

Transport Quebec has suggested detours during this phase of construction.

Transport Quebec spokesperson Mario St-Pierre said he knows it's inconvenient, but it's necessary.

"A detour is never as good as the original path, but what we suggest here is to move along on the highway, take an exit and go back the other way. This is the best thing to do, to avoid the local streets because it would be worse. Of course there will be some delays and inconveniences related to that, but it takes time for people to get used to that," he said.

As many as 25,000 drivers use the routes every day.
