Driving routes to get from downtown Kingston to the east end will be reduced this coming weekend.
Public Services and Procurement Canada says the LaSalle Causeway will be closed to vehicles and boats from 9:30 p.m. Friday until 6 a.m. Monday.
Pedestrians and cyclists will have periodic access throughout the weekend.
The closure is needed to install mechanical equipment and replace structural components on the lift bridge.
The schedule could change depending on weather.
