Sherbrooke and Notre-Dame Streets Roundabout

gbi is proud to have participated in the first major traffic roundabout in Quebec. We carried out the feasibility and traffic studies; the layout concept; the draft design and final design reports; the plans, specifications, and site supervision for the roadway and railway viaduct reconstruction, and for the development of a roundabout (Sherbrooke Street, Notre-Dame Street and the approaches to the Le Gardeur Bridge), including the demolition of a road bridge paired with a railway bridge that was to remain.
