Dear Resident or Park User,
The Jacques Cartier and Champlain Bridges Incorporated (JCCBI) would like to advise you that the north section of Léon-Gravel Park has been chosen as a temporary work site during fall/winter 2021-2022 as part of the deconstruction of the original Champlain Bridge. JCCBI, the Nouvel Horizon Saint-Laurent (NHSL), and The St. Lawrence Seaway Management Corporation (SLSMC) selected this site following a series of multi-criteria analyses.
Located at the tip of the St. Lawrence Seaway turning basin, this area is the only accessible location near the work site that has sufficient water depth to temporarily dock a barge without affecting boating activities. Thanks to the site’s configuration, no trees will have to be cut down, although note that young plants or small shrubs may have to be pruned or cut back. The contractor will make partial use of the park’s access roads and parking areas.
To ensure that the work is aligned with the environmental assessment process that began in 2013, the project’s Targeted Environmental Analysis (TEA) is currently being modified. This modification includes inventories (of wetlands, Boreal chorus frogs, brown snakes, etc.) to characterize the area and identify the impacts of the work on this environment with the addition of mitigation measures, if necessary.
JCCBI and NHSL are therefore communicating with the public through this advisory as part of the modification to the TEA. Please feel free to share your questions and concerns with us (see contact information below) so that we can take these into account during the TEA process.
Figure 1: Lowering of the suspended span
This temporary work will be carried out during the park’s low-use period (November 2021 to the end of April 2022). It will consist of docking onto a temporary jetty a barge that will transport the suspended span of the original Champlain Bridge (Figure 1 opposite). Once the barge is docked, the span will be dismantled on site.

This work will be carried out by about a dozen workers during the day (7:00 a.m. to 7:00 p.m.) on weekdays. From February to March 2022, 3 to 4 trucks per day will pass through the area.
* The work schedule is subject to change.
A signage and traffic plan (with flaggers on site as required) will be implemented so that people can safely use the park during the work. Even if partially occupied by the contractor, the parking area will be accessible during the entire work period. The work area will also be clearly demarcated, and the site will be monitored to prevent trespassing.
Different measures will be put in place as part of the Champlain Bridge deconstruction project to minimize the impact of activities on the environment and citizens’ quality of life. For example, NHSL must limit its transportation hours and maintain the site access points to control dust emissions. The contractor will also relocate the brown snakes at the site.
The contractor must comply with the established noise and air quality standards. Although the work is not expected to exceed the criteria in nearby residential sectors, these levels will nevertheless be monitored during the work.
The contractor must also leave and restore the site by the end of April 2022 so that the park is ready for the peak season.
