As Montreal's Samuel De Champlain Bridge nears completion, deconstruction plans for the 1962-built steel truss cantilever span it replaces are coming into focus. The Government of Canada has announced that Jacques Cartier and Champlain Bridges Incorporated (JCCBI) has been selected to oversee the deconstruction process, which is expected to take three years to complete.

JCCBI launched a pre-planning study in 2017 to explore the best options for deconstruction, which is estimated at a cost of $400 million. Infrastructure Canada says additional information about the deconstruction method will be made available to the public in the coming months.

The new $4 billion project bridge is being constructed in a public-private partnership with Signature on the St. Lawrence, who will be responsible for operating the service for a 30-year period. The cable-stayed bridge has been designed to handle higher volumes of traffic on a vital route for freight transportation between Canada and the United States.

JCCBI is a Canadian Crown corporation, operating at arms-length from the government, with a mandate to maintain numerous federal structures in the Montreal area, including the existing Champlain Bridge. the Jacques Cartier Bridge, the Melocheville Tunnel, and the Bonaventure Expressway.
