Parks Canada will be replacing the upper and lower lock gates at Lock 20 – Ashburnham in Peterborough from November through April, and is installing a temporary bridge to allow access to the Trans Canada Trail during the construction period.

The trail at Lock 20 between Beavermead Park and Rogers Cove will be closed on Friday (November 7) from 9 a.m. to 1 p.m. so Parks Canada can install the temporary bridge that pedestrians would use over the next six months in lieu of crossing at the top of the lock gates.

Also known as a Bailey bridge, the temporary bridge is a type of portable and pre-fabricated truss bridge that will provide a safe and functional crossing while the replacement work is completed.

The Trans Canada Trail crossing at Lock 20 will reopen to the public once the Bailey bridge installation is complete on Friday, and will remain accessible until construction begins on the gate replacement work and the Bailey bridge goes into use.

In October, Parks Canada erected construction fencing from south of Maria Street to just north of the trail at Lock 20 to prevent vehicle and pedestrian access, including along the canal road.

“Parks Canada appreciates the public’s understanding and cooperation as we work to ensure the continued safety, functionality, and long-term sustainability of the Trent-Severn Waterway,” read a media release from Parks Canada.

Construction fencing is in place at Lock 20 - Ashburnham in Peterborough in advance of a Parks Canada project to replace the upper and lower lock gates from November 2025 through April 2026. Access to the Trans Canada Trail across the lock will be temporarily closed on November 7, 2025 so Parks Canada can install a temporary bridge to allow pedestrian access to the trail during the construction period.
