A multi-stage project

Rue De Bleury to Peel

The redevelopment work on rue Sainte-Catherine Ouest, between rue Peel and rue De Bleury, on square Phillips and on avenue Union, juxtaposed with the square, has been completed and marks the transformation of the thoroughfare.

The widened sidewalks, cobbled surfaces, numerous trees and new seating areas restore the titles of nobility to these urban spaces in the city centre.

Rue Peel to Rue Saint-Marc 

The work, which covers more than a kilometer, will be carried out in sections between Peel and Saint-Marc streets until 2030. Follow the progress of the work currently underway.
