Champlain Bridge deconstruction

Work Blitzes | Fall 2022
When did the work start and what progress has been made to date?

Progress update as of Aug. 30, 2022. (started in August 2020- 26 months ago)

  • Overall percentage of completion is 67 %
  • 2 abutments
  • 39 spans
  • 38 piers
  • 26 footings
What are the works planned for this fall?

Major work blitzes will take place this fall in the Brossard sector. The spans above Hwy. 132 as well as their supporting piers will be demolished in a key milestone for this important project.

What are the expected impacts on traffic?

Overall, six weekend blitzes are required and will be carried out from 11:00 p.m. on Friday to 5:00 a.m. on Monday. Depending on the work, either Hwy. 132 or Marie-Victorin Blvd. will be completely closed in one or both directions. September will also have 6 complete weeknight closures of Marie-Victorin Blvd., (including its access and exit ramps). Since this work is weather-sensitive, the dates may change.

What are the blitzes schedule?

Removal of modular trusses (weather-sensitive work)

  • September 16-17-18
  • September 23-24-25
  • Sept. 30 - Oct.1-2
    • October 7-8-9 + October 14-15-16: if the work is postponed

Demolition of spans, piers and footings: Hwy. 132 and Marie-Victorin Blvd.

  • November 4-5-6
  • November 18-19-20
  • November 25-26-27

** Dates may change depending on the weather or work progress

What will be the detours during these major closures? Will users circulate in residential areas?

For most of these hindrances, the priority detours are on the highway network, but in some cases, detours may be planned via Simard and Lapinière boulevards in Brossard.

Highlights
Do you coordinate your work with your other partners?

JCCBI is an active member of Mobility Montréal and actively participates in various work coordination committees with all of Mobility Montréal’s partners to minimize the impacts of road and public transit projects on traffic.

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. 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 began in July 2020 and will end in January 2024, which means 43 months. 

How much will it cost to deconstruct the Champlain Bridge?

The overall envelope planned for the deconstruction project is $ 400 million and includes, among other things, deconstruction work ($225,7), environmental protection measures, the materials reuse program as well as the research and development program, in addition redevelopment of the shoreline at the end of the project (Héritage Champlain).

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. 

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

As part of the Heritage Champlain 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 is online. More information to come on Heritage Champlain.

Will citizens be able to get a part of the bridge as souvenir?

The Champlain Bridge had a big social and economic impact on the Greater Montreal landscape. JCCBI would therefore like to offer the public souvenirs to commemorate its significance. Details to come in 2022.

What will the catamaran barge be used for?

The catamaran barge will be used to deconstruct the original Champlain Bridge’s 30 spans over the St. Lawrence River by NHSL and its partners, who developed this unique tool that is 76 m long by 41 m wide (250 ft. long x 132 ft. wide), or an area equivalent to two NHL hockey rinks. The catamaran barge consists of two single-hull barges connected by steel caissons and beams welded to the barge decks.

This catamaran barge, which will travel along the river, is equipped with a system of six lifting towers that can support up to 4,800 tonnes and that will hold the deconstruction platform. Added to this remarkable machine will be about a dozen hydraulic systems designed to frequently move huge components with loads of over 30,000 pounds. 

Will it be operational during winter?

The barge’s winter operations will be more or less the same as in summer. However, during the winter, adaptations will be set up to protect the catamaran barge, and ice management will be put in place upstream from the barge.

Where will the materials be transported to?

The materials will be transported and reused locally, near the project site, by specialized companies for each type of material. 

Why did you decide to deconstruct instead of demolish the bridge?

JCCBI prioritized the environment and the quality of life for local residents. This choice requires meticulous deconstruction methods and prohibits faster methods such as blasting. With a focus on sustainable development, a project goal is to reuse the vast majority of the deconstructed materials. A materials management and reuse plan was developed to provide a framework for reuse and recycling options depending on the type of recovered materials. Overall, the Nouvel Horizon Saint-Laurent (NHSL) Corporation (the contractor for the project) is aiming to recover a minimum of 90% of all deconstruction materials from the original Champlain Bridge.

What measures are in place to minimize nuisances (dust, noise, traffic and debris management)?

JCCBI is closely monitoring all nuisances (noise, vibrations or dust). NHSL is committed to upholding these criteria and has put everything in place to stay within these thresholds throughout the work. If necessary, NHSL will propose additional measures to ensure compliance with these criteria. 

Do you have a research and development program?

JCCBI launched an applied research program to significantly improve our knowledge of infrastructure performance and sustainability. The research program will be conducted in collaboration with different Canadian research bodies. JCCBI selected 12 research and development projects that will take place during the deconstruction.
