Weekend traffic update: major closures on Champlain Bridge, Turcot interchange

The Highway 15 South is completely blocked through the Turcot interchange.

MONTREAL – Major closures will limit access to downtown and likely contribute to traffic on highways and bridges around the city this weekend. The Champlain Bridge and the Highway 15 through the Turcot interchange are at the epicentre of significant closures.

Transports Quebec issued a recommendation on Thursday, advising drivers to prioritize carpooling and public transport.

“A reminder that several measures to prioritize public transport have been in place since 2011 with the objective of reducing the traffic impacts of the Turcot interchange project,” the agency wrote.
