Project overview

Every day, about 2,500 trucks transit through the Port of Montreal’s facilities, resulting in traffic issues on Notre-Dame Street. The objective of the overpass project is to improve road accessibility to the Port of Montreal and alleviate trucking. To achieve this, the project aims to create a direct link between the Port of Montreal and the highway, ensuring a continuous movement of containers to and from the terminals. This project includes architectural integration, an artistic component from the Guido Molinari Foundation, and landscaping. Total cost: $47.8 M.


Sustainable project work

  • Rainwater management using drainage ditches that let the rainwater infiltrate the water table
  • Integration of such innovative measures as using recycled glass in some of the concrete components
  • Extension of the embankment between the Port's rail network and Notre-Dame Street
  • Preservation of as many of the area's 520 trees as possible through landscaping that cuts the fewest trees possible and showcases the remaining trees
  • Two trees planted in replacement for every tree cut
  • Lighting in compliance with International Dark-Sky Association (IDA) standards
  • Landscaping (laying a stone dust footpath to promote water infiltration and installing bike racks and park benches)
  • Architectural integration with the Molinari Foundation's artistic concept
