Blitz during upcoming weekend for the Highway 15, with the road disruptions associated

*Dates subject to change. In the event of adverse weather conditions or operational constraints, the work or road closure mentioned in this notice could be postponed to a subsequent weekend.

Weekend of July 27 to 30 *

Signature on the Saint Lawrence team plans to carry out a blitz of work, which will take place day and night, to complete and open on July 30 at 5 am *, the new south direction of the A15, from LaSalle to L’Ile-des-Soeurs.

To carry out this blitz, a complete closure of the A15 South is necessary. The entire section will be closed from Friday, July 27 * from 10 pm to Monday, July 30 * until 5 am, from the Turcot interchange to L’Île-des-Soeurs.

Other major closures are expected during the summer, done as part of the construction of the New Champlain bridge but also  adjacent project, including the projects Turcot Interchange and Bonaventure Highway.


Opening of the temporary configuration without permanent noise barrier

he complete opening of the A15 South to temporarily accommodate traffic from the north and south directions will be done without the presence of permanent noise barriers, which will be installed during the fall between LaSalle and Wellington. In the meantime, temporary noise barriers will remain to mitigate noise from our work as well as the temporary configuration. Considered as a site area, SSL is required to meet the noise criteria included in the partnership agreement with the Government of Canada. SSL will regularly monitor the noise generated by these construction activities. The Citizen’s forum section of our website, under Works and Impacts, presents the results of the sound measurements.


Back to normal to access L’Île-des-Soeurs from the A15 South

At July 30* in the morning, a new configuration of exit 57-S will make it possible to reach the boulevard de l’Île-des-Soeurs from the A15 South, like before. The 57-N exit will also be reopened by July 30 *.


Closing of René-Lévesque boulevard from August 6* to August 20

Following the opening of the new A15 South, including the reopening of exits 57-S and 57-N, a complete closure of René-Lévesque boulevard between the Champlain Bridge and the Claude-Robutel roundabout will take place until Monday, August 20th. With the exception of concreting carried out at night, the majority of activities will be done by day.
