Public Services and Procurement Canada (PSPC) has identified 21 days this summer and fall during which the temporary bridge on the LaSalle Causeway will be removed to allow marine traffic to pass.

The causeway is a main traffic link between Kingston’s downtown and east end, but its former bascule bridge was damaged last year and could not be repaired. The bridge was removed and replaced by a temporary modular bridge, which is expected to remain in place until the construction of the permanent replacement bridge begins.

The modular bridge must be periodically removed to allow ships to pass the crossing that connects the Cataraqui and St. Lawrence rivers. The LaSalle Causeway is the southern terminus of the Rideau Canal system that connects the St. Lawrence with the Ottawa River.

The 2025 navigation season on the Rideau Canal runs until Oct. 13.

PSPC says the LaSalle Causeway will be fully closed to vehicles, cyclists, and pedestrians to allow for the temporary opening of the main marine navigation channel during the following periods:

• Sunday, June 8, from 6 a.m. to 10 p.m.
• Sunday, June 15, from 6 a.m. to 10 p.m.
• Sunday, June 22, from 6 a.m. to 10 p.m.
• Sunday, June 29, from 6 a.m. to 10 p.m.
• Tuesday, July 1, from 6 a.m. to 10 p.m.
• Sunday, July 6, from 6 a.m. to 10 p.m.
• Sunday, July 13, from 6 a.m. to 10 p.m.
• Sunday, July 20, from 6 a.m. to 10 p.m.
• Sunday, July 27, from 6 a.m. to 10 p.m.
• Sunday, Aug. 3, from 6 a.m. to 10 p.m.
• Sunday, Aug. 10, from 6 a.m. to 10 p.m.
• Sunday, Aug. 17, from 6 a.m. to 10 p.m.
• Sunday, Aug. 24, from 6 a.m. to 10 p.m.
• Sunday, Aug. 31, from 6 a.m. to 10 p.m.
• Sunday, Sept. 7, from 6 a.m. to 10 p.m.
• Sunday, Sept. 21, from 6 a.m. to 8 p.m.
• Sunday, Oct. 5, from 6 a.m. to 8 p.m.
• Tuesday, Oct. 14, from 6 a.m. to 8 p.m.
• Sunday, Oct. 19, from 6 a.m. to 8 p.m.
• Sunday, Nov. 2, from 6 a.m. to 8 p.m.
• Sunday, Nov. 16, from 6 a.m. to 8 p.m.

“During these periods, the removal of the modular bridge will begin at 6 a.m., with the marine channel expected to be open by 9 a.m. From June 8 to Sept. 7, the marine channel will be closed at 7 p.m. to reinstall the bridge, with the causeway expected to reopen to vehicles, cyclists and pedestrians by 10 p.m,” PSPC says. “From Sept. 21 to Nov. 16, the marine channel will be closed at 5 p.m. to reinstall the bridge, while the causeway is expected to reopen by 8 p.m.”

Boaters are encouraged to cross the causeway as early as possible during the opening window as reinstallation of the modular bridge may need to be done sooner depending on marine conditions.

A timeline for the construction of a permanent replacement bridge on the LaSalle Causeway has yet to be confirmed.
