If your morning commute takes you through the tunnel under the Lift Lock in Peterborough’s East City, you may need to take another route on Monday morning (June 1).

Parks Canada will be closing the single-lane tunnel, which connects Hunter Street East with Ashburnham Drive, from 9:30 a.m. until noon on Monday.

The closure is needed to allow for work on the embankment, immediately east of the tunnel, as part of Parks Canada’s multi-year infrastructure project along the Trent-Severn Waterway.

The project includes rehabilitation of earth dams along the canal, sealing of leaks in the Lift Lock, and the complete replacement of the Maria Street Swing Bridge. The entire project is expected to take up to four years to complete, with the bridge replacement scheduled to begin in the fall.

During the temporary tunnel closure, a signed detour route will be in place and traffic control personnel will be on-site to assist with the movement of emergency services vehicles, transit buses, and heavy trucks.

Parks Canada says drivers should expect delays and are encouraged to plan their travel accordingly. Nearby alternate routes across the canal include Maria Street to the south and the McFarlane Street bridge to the north.
