Rehabilitation work along Trent-Severn Waterway

Starting in 2026, Parks Canada is undertaking infrastructure upgrades along the canal corridor from Lock 20 to McFarlane Street Bridge and the Maria Street Swing Bridge, part of the Trent–Severn Waterway National Historic Site in Peterborough.

The work includes rehabilitation of the Peterborough Earth Dams, repairs at the Peterborough Lift Lock, and replacement of the Maria Street Swing Bridge.

The City is sharing this information to help direct residents and businesses to the appropriate source. Road closures and detour routes will be announced as work progresses.

For detailed project information, scope of work, timelines, impacts and updates, please visit Parks Canada’s website.
