Work on the renovation of Route 340 (Cité-des-Jeunes Blvd.) will resume on April 15
The ministère des Transports et de la Mobilité durable is informing road users that reconstruction work on Route 340 (Boulevard de la Cité-des-Jeunes) will resume on April 15 and continue until the end of November 2026. The work, which will take place in Vaudreuil-Dorion, will involve a new phase of construction, including the building of two roundabouts east of Highway 30, the redesign of two intersections near the new hospital, and the construction of a one-kilometer-long dedicated multi-use path that will extend the current multi-use path to the future hospital. Construction will then pause for the winter and resume in the spring of 2027. All work is scheduled to be completed in 2028.
