Deconstruction of the bridge, which had reached the end of its service life, started in summer 2020 and will continue until January 2024.

The original Champlain Bridge deconstruction is the largest project in JCCBI’s history and is a unique project for Quebec. Its overall $400M envelope includes:

  • Deconstruction work at a cost of $225.7M 
  • Environmental protection measures 
  • Material reuse and Research & Development programs 
  • Redevelopment of the shoreline at the end of the project  

The deconstruction work is being carried out by the Nouvel Horizon Saint-Laurent (NHSL) group formed by Pomerleau Inc. and Delsan-A.I.M. Environmental Services Inc.
