Highway 20/30 Interchange Redevelopment

Construction, Repair and Reconstruction

Our team was awarded the mandate to build, repair and rebuild the Highway 20/30 interchange in Boucherville.

Our work was as follows:

• Building a new structure and completely rebuilding two structures and their approaches.
• Repairing the existing structures (which were in critical condition).
• Preparing for the transition of Highway 30 (2 x 3 lanes)
• Preparatory work for traffic shifts.
• Strengthening a structure temporarily.
• Building a new structure between two existing structures.
• Building 1 km of retaining walls.
• Building lightweight backfill approaches (100,000 m³).
• Excavation (210,000 m³) and backfill (300,000 tonnes).
• Installing intelligent transportation systems, overhead signage and electrical facilities.
• Drainage.
• Landscaping.

Despite a tight schedule, a high-traffic site and specialized work, we completed the project efficiently and accurately within the stipulated timeframe.

High-Traffic Site

Traffic was constant in the work area, making the site very busy.

Specialized Work Required

Our own teams carried out extensive work in various specialties, such as building retaining walls, installing driven piles, earthwork, drainage, formwork and casting concrete.

Tight Schedule

We completed the mandate within the client’s strict timeline.
