Notice of Traffic Disruption – Redevelopment Work at the A-640 / Roland-Durand

The Town would like to inform you that, from August 3 to October 1, the first phase of construction will take place to install two one-way cycling paths separated from both vehicular traffic and sidewalks beneath the Highway 640 overpass. This dedicated cycling link will connect Roland-Durand Boulevard in Rosemère to René-A.-Robert Boulevard in Sainte-Thérèse.


During this period:

  • A portion of the access ramp to Highway 640 West from René-A.-Robert Boulevard will be closed. Heavy vehicles will not be permitted to use this ramp. 
  • The sidewalk and the right-hand lane will be completely closed in both directions beneath Highway 640. 
  • The sidewalk and the right-hand lane on Roland-Durand Boulevard, northbound, will be completely closed. 


For everyone’s safety, please follow the posted signs.


It is the responsibility of road users and affected parties to plan and adjust their travel accordingly.
