The Ministry of Transportation and Sustainable Mobility is informing the public that, beginning Saturday, June 13, construction work and road closures will take place on a section of Highway 13 in Laval and continue through the fall.

These disruptions are due to the reconstruction of a southbound section of Highway 13 between Dagenais West Boulevard and Highway 440 (Jean-Noël-Lavoie).

The project will require traffic detours and dynamic lane management for several weeks, extending until the fall season, which officially begins on September 22.

Traffic Management

During this phase, the southbound lanes of Highway 13 between Sainte-Rose Boulevard and Highway 440 will be completely closed at all times.

Traffic will be diverted onto the southbound service road, which has two lanes.

However, during the morning rush hour (Monday through Friday), an additional lane will be made available on the opposite carriageway of the highway (through a contraflow traffic configuration), providing a third southbound lane.

The Ministry notes that these traffic configuration changes will be implemented overnight, between 2 a.m. and 4 a.m., as well as between 11 a.m. and 1 p.m., through dynamic lane management.

The right shoulder of the southbound service road will remain reserved for buses during the morning peak period.

Additional Closures

Throughout the project, the following nighttime closures are also planned: partial closures of northbound Highway 13, partial closures of the southbound service road, and complete closures of the access ramps from Dagenais West Boulevard.

Speed limits may be reduced within the construction zone to 70 km/h on the southbound express lanes, 90 km/h on the northbound express lanes, and 60 km/h on the southbound service road.

Motorists should expect periods of congestion. The Ministry recommends allowing extra travel time when driving through the area.

During full closures, detour routes will be clearly marked with temporary signage.

Other Important Information

The work may be postponed, extended, or cancelled due to adverse weather conditions or operational constraints.

Before travelling, motorists are encouraged to consult Québec 511, a useful tool for planning trips and obtaining up-to-date road conditions.

The Ministry thanks road users and local residents for their cooperation and reminds everyone that respecting posted signage is essential for the safety of both motorists and construction workers.
