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: $33.3M.
