Montreal's Champlain corridor hit with long weekend construction

Although it is a holiday weekend, construction crews are at work on the Champlain corridor as well as on the Mercier Bridge, and this means lane closures throughout the three-day weekend.

Closures are scheduled between Friday at 8 p.m. ET and Tuesday at 5 a.m. ET.

The Bonaventure Expressway will be partly open.

Heading towards the Champlain Bridge, two out of three lanes will remain open, and Exit 4 to A-15 South and North is closed.

Heading towards downtown Montreal, one of the three lanes will remain open, and Exit 1 to Wellington is closed.

The access ramps from Moulins Road East (Ramp J) and from Moulins Road West (Ramp C) is closed.
