Road closures are going to be particularly brutal this long weekend as Transport Quebec has planned extensive highway closures in and around Montreal.

On Saturday evening, three bridges connecting the South Shore to the Island of Montreal will be closed: the Mercier Bridge for construction work, the Champlain Bridge for connection to the new bridge, and the Jacques-Cartier Bridge because of the fireworks.

Drivers are encouraged to plan their journeys accordingly and use public transportation if possible.

Champlain Bridge

Highway 15 South and the Bonaventure Expressway between the Turcot Interchange and Taschereau Blvd. will be closed from 10 p.m. June 28 until 11 a.m. July 1 as crews prepare to open southbound lanes of the new Champlain on July 1. The new bridge will be opened in both directions as of 11 a.m. on Canada Day.

That means as of 11 a.m., there will be a complete closure of Decarie 15 south / Hwy 10 east between the Turcot Interchange and the entrance to Taschereau Blvd. in Brossard, including the Champlain Bridge.
