ROADWORK ANNOUNCED - IMPACT ON OUR DAILY COMMUTE

To the attention of parents, staff members and transportation companies,

We have been informed that the Ministry of Transport will be undertaking major reconstruction work on the Highway 520 (Côte-de-Liesse) overpass at Cavendish Boulevard. As this work falls under the responsibility of the Ministry, the situation is clearly beyond our control.

As you can imagine, these repails will result in major traffic disruptions, particularly beginning in March 2026. Preparatory work for the construction site will begin on February 10, 2026.

We understand that an adjustment period will be necessary for everyone, parents, students, transportation companies, staff members, and other partners of our educational community. As such, we will all need to plan to leave earlier and arm ourselves with a little extra patience.

Some adjustments or changes may be made along the way, depending on the progress of the construction and traffic conditions. The school is also working closely with transportation companies to ensure that bus routes are affected as little as possible by this situation. Please be assured that we are committed to keeping you informed of any relevant developments.

For additional details, we invite you to consult the official memo (In french only) issued by the Ministère des Transports et de la Mobilité durable.

This document includes the explanatory diagram below, illustrating the phases of the work, the expected obstructions, and the detours.
