LaSalle Causeway
Information for motorists, marine and other traffic

The Lasalle Causeway’s Bascule Bridge was demolished on June 20, 2024 due to a construction incident on March 30, 2024. This incident resulted in disruption to local traffic and marine navigation. On October 3, 2024, a modular bridge was put in place, restoring bridge traffic for the City of Kingston.

Modular bridge access for land traffic

The modular bridge is currently open to vehicles, cyclists and pedestrians. During the marine navigation season, the bridge will close on scheduled dates to open the main navigation channel to marine traffic.

Main navigation channel access for marine traffic

During the marine navigation season, the main navigation channel reopens to marine traffic on scheduled dates.

Consult the Schedule for marine navigation of the main channel for more information.

Secondary channel boat access: Vertical clearance gauges at the East Bridge

We’ve installed staff gauges on the central pier of the East Bridge at the LaSalle Causeway. These help boat operators safely navigate the secondary channel at the causeway.

The gauges are easy to see and show the vertical clearance between the underside of the bridge and the surface of the water (the clearance height). They are fixed boards with reflective markings on the north and south faces of the pier. They show the vertical clearance height in feet.

We also installed a device that electronically determines the East Bridge vertical clearance for boats. The maximum vertical clearance is shown online (below) and updated every hour. Boaters can check it remotely to help plan their trip through the causeway. Vertical clearance readings are reported during the navigation season only, from approximately mid-April to mid-November.
