The Turcot Interchange Reconstruction Project in Montreal, Quebec involves replacing several run-down structures. New structures include the Saint-Jacques Street overpass that crosses the Décarie Expressway (Autoroute 15), for which 2,100 tons of steel components are currently being fabricated at Canam’s plant in Quebec City, Quebec. The shape of the bridge’s structure recalls airplane wings due to the wings on either side of the central girders.
The 394-foot (120-metre) long cable-stayed bridge with a steel monocoque structure will consist of a combination of box girders coupled with an orthotropic steel deck. Canam will manufacture five box girders, 30 orthotropic deck panels and one steel tower as well as the complex anchoring system that will be part of the main structure of the bridge. Canam will also provide Goodco Z-Tech structural pot bearings, seismic isolators and modular expansion joints for this project. To date, 70% of the steel components have been fabricated, and delivery to the job site has begun. The bridge will be completed in the fall of 2018.
The Turcot Interchange was first opened to traffic in April 1967. On average, over 300,000 vehicles use it on a daily basis.
