Planning is officially underway for the long-awaited reconstruction of Montreal’s Saint-Pierre interchange.
The Quebec government says the project has entered its planning phase and will be delivered through a collaborative approach involving designers and builders from the outset. The new interchange will feature elevated structures designed to improve connections to the Saint-Pierre neighbourhood, while also including dedicated infrastructure for public transit and active transportation.

Over the next several years, the province will complete environmental assessments, refine the project’s design and continue consulting with the City of Montreal, local boroughs, residents and businesses.

Built in 1966, the Saint-Pierre interchange links Highway 20 and Route 138 and is a key transportation corridor connecting downtown Montreal, Trudeau International Airport, the West Island and the South Shore. Preventive maintenance will continue on the existing interchange until the new structure is built.
