Deconstruction of the original Champlain Bridge

The goal of the TEA is to evaluate the impacts of possible deconstruction methods and determine whether the mitigation measures and goals set out in the 2013 environmental study are still appropriate or whether they need to be improved or replaced based on best practices in 2020 and the lessons learned during the construction of the new bridge.

The TEA addresses multiple environmental components:

• Soil, water and air quality;
• Greenhouse gases;
• Noise levels;
• Wildlife and plant life;
• At-risk species;
• Boating activities;
• Maintaining economic activities on the St. Lawrence Seaway.

The analysis also includes studies on mobility and the impact of truck traffic. The many mitigation measures JCCBI plans to implement include three compensation programs:

• Fish habitats and wetland areas;
• Greenhouse gases;
• Cliff swallow habitats.
