Project name

New Bridge for the St. Lawrence Corridor Project (New Champlain Bridge Corridor Project)


The New Champlain Bridge Corridor (NCBC) Project includes the replacement of the Champlain and L'Île–des–Soeurs bridges with a 3.4 kilometres bridge. The Project will widen the federally owned portion of Highway 15 to a six–lane capacity. The NCBC Project is being 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;
  • Improve the flow of people and goods in the Montreal area;
  • Improve the safety of users through modern design aspects;
  • Design and construct the new Champlain Bridge and Ile des Soeurs Bridge with 125 Year Life Expectancies;
  • Design and construct a public transit corridor and highway 15 that meet engineering standards;

Industrial benefits

The NCBC Project will foster economic growth by improving connections across road systems and ensuring the continuous and safe flow of people and goods. The project is a crucial corridor for the regional economy and for Canada as a whole. 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.

In addition to ensuring the safety of users, replacing the existing infrastructures and widening Highway 15 will mitigate disruptions to the trade corridor and will improve the flow of traffic.
