Why does the Champlain Bridge have to be deconstructed?


The Champlain Bridge has reached the end of its service life and has to be taken down. Due to design problems with the original bridge, some structural components have deteriorated more quickly than expected. Even without vehicle traffic, maintaining this structure would result in significant annual maintenance and inspection costs of $4 million to $7 million (excluding major work required to quickly repair deficiencies detected during inspections). The weight of the bridge alone (dead load) accounts for 80% of the total load, while traffic (live load) only accounts for 20% of the total load.

When will the bridge be deconstructed and how long will it take to deconstruct?


Deconstruction work will begin in the spring of 2020. The timetable and deconstruction methods of the Champlain Bridge will be defined with the selected consortium, New Horizon St-Laurent, but we are estimating the total duration of the work at 3 years.

How much will it cost to deconstruct the Champlain Bridge?


The preliminary assessment for the deconstruction of the Champlain Bridge is approximately $400 million, and includes the deconstruction work, the transportation of materials, the material reuse, implementing the environmental protection measures, carrying out the research and development program and developing the shoreline at the end of the project, the Heritage Champlain program.

Will there be more major traffic hindrances during this work?


Not for the moment, as most of the work will be done from the St. Lawrence River without any major hindrance to traffic. However, partial traffic hindrances will be required on Hwy. 132 in Brossard when the spans are removed over this road as well as partial hindrance on René-Lévesque Blvd. in the Ile-des-Soeurs sector. 

Will public consultations be held?


Yes, residents were invited to learn about the project during information days held on May 8 to 9 2019 at the Centre for Sustainable Development, on May 11 2019 at the Elgar Community Center in L’Île-des-Sœurs, and on May 13 2019 at the Alphonse-Lepage Cultural Center in Brossard.

How will the Champlain Bridge be deconstructed?


The bridge will be deconstructed and not demolished. This means that its components will be carefully taken apart to minimize the impact on the environment and the public. The exact deconstruction method will be determined by the contractor, and the goal will be to create social, environmental and economic benefits in accordance with sustainable development principles.

Have you done an environmental study?


Yes, JCCBI is conducting a targeted environmental analysis (TEA) to enhance the environmental study conducted by Infrastructure Canada in 2013 for the construction of the Samuel-De Champlain Bridge, as this report also covered the deconstruction of the existing bridge.

What are you going to do with the bridge materials?


JCCBI is deploying an ambitious program to optimize material reuse, particularly by integrating components of the Champlain Bridge into artistic, cultural or infrastructure projects. Other approaches include promoting the reuse of non-processed materials as well as recycling at local or non-local sites. JCCBI will also implement mitigation measures to reduce the project’s overall greenhouse gas emissions as much as possible.

The materials to be recovered or reused include an estimated 250,000 tonnes of concrete, 25,000 tonnes of steel, and 12,000 tonnes of asphalt.

What will be given to the community to commemorate the Champlain Bridge?


As part of the Champlain Bridge Heritage program, JCCBI will ensure that the community has a historical legacy of this bridge. In addition, a Heritage Champlain co-design workshop was organized in December 2019 with citizens who had expressed their interest during the public consultations. The report of this workshop will be online soon.
