Supplementary Information Table: Status Report on Transformational and Major Crown Projects

Project name

New Bridge for the St. Lawrence Corridor Project


The existing Champlain Bridge is one of the busiest bridges in Canada with traffic estimated at over 40 million vehicles per year. It is a major Canada-United States trade corridor, handling $20 billion of international trade and 11 million transit commuters per year.

The New Bridge for the St. Lawrence Corridor (NBSL) Project addresses the need to replace the Champlain Bridge and the temporary causeway (which is being built as a temporary replacement to the Nuns' Island Bridge), both having reached the end of their useful lives. The Project also offers an efficient solution to the movement of goods and people by widening the federally owned A15 Highway to a six-lane capacity. The NBSL Project is expected to be delivered as a public-private partnership (P3).

Project outcomes

  • Maintain the Safety and Efficiency of the Corridor;
  • Foster Sustainable Development and Urban Integration within the Montreal area;
  • Improving the Flow of People and Goods in the Montreal Area;
  • Improving the Safety of Users Through Modern Design Aspects;
  • Designing Bridges for the St Lawrence, and Nuns' Island with a 125 Year Life Expectancies;

Industrial benefits

Replacing the existing infrastructures, as well as widening the A15 Highway will mitigate any risk of disrupting the trade corridor and will improve the flow of traffic.

The project provides significant opportunities for local business to participate, notably in construction related aspect of the project's implementation.

The NBSLC Project will provide lasting economic benefits to the municipalities on each side of the river and more broadly to the region as a whole.
