Public Services and Procurement Canada (PSPC) wishes to provide information regarding the upcoming scheduled works for the Bascule Bridge at the LaSalle Causeway in Kingston, Ontario.

This project will address health and safety risk, as well as operational risks, posed by the current condition of various components of the lift bridge as they are beyond their service lives. Planned work for the bridge includes replacement of the steel deck grating and supporting stringers, rehabilitation of the deteriorated concrete on the counterweight, and strengthening of the supporting steel truss members at the main trunnions.

Work is scheduled to take place during the navigation off-season, from November 1st 2023 to April 30th 2024, and from November 1st 2024 to April 30th 2025. During construction, the following impacts to vehicular, marine, and pedestrian traffic can be expected:

 Throughout the duration of the construction works, the bridge will be reduced to a single lane of alternating traffic. Vehicular traffic will still be able to access the bridge during these times using alternating lanes.

  • A number of full closures to vehicular traffic will be required at various points in the construction schedule. Full closures will be kept to the minimum extent possible to permit completion of the rehabilitation work and will be scheduled for off-peak hours. Public notices about the closures will be issued in advance and shared through our social media channels.
  • Due to the nature of the work, the bridge will be unable to lift for marine traffic throughout the construction period. The bridge will continue to lift as usual from May 1 to October 31st each year.
  • Pedestrians and cyclists will be able to continue using the bridge via a temporary sidewalk constructed alongside the existing bridge, but periodic delays are still expected.

PSPC is committed to ensuring that the LaSalle Causeway remains safe and operational for users. We will continue to engage with stakeholders as the project proceeds.   For more information:
