Peterborough Earth Dams Rehabilitation and the Maria Street Swing Bridge Replacement

PETERBOROUGH, ON – February 19, 2026 - In the coming weeks, work will begin on a coordinated, multi-year infrastructure project along the Trent–Severn Waterway National Historic Site in Peterborough that includes:

• rehabilitation of the Peterborough Earth Dams to improve canal embankment slope stability and erosion protection between Lock 20 and McFarlane Street Bridge, increasing safety along the canal corridor;
• repairs and maintenance of the Peterborough Lift Lock to address water infiltration; and
• replacement of the Maria Street Swing Bridge to support continued safe use and increase its vehicle load carrying capacity while preserving the heritage landscape.

Mobilization will begin today; no closures are expected during this initial phase.

Work within the canal will be scheduled outside of the operational season to minimize impacts on navigation. Temporary road closures, detours, and short-term restrictions on pathways, sidewalks and green space will occur during construction. Parks Canada is working closely with the City of Peterborough to coordinate traffic diversion and to reduce impacts for emergency services and public transit. Advance public notice will be provided ahead of any major closures or changes.

Parks Canada will provide regular project updates through a dedicated project webpage and an email subscription list. A public information session is planned for March 2026, and more details, like the construction phases, timelines, and closures, will be shared shortly.

This work will ensure public safety and the responsible stewardship of the Trent–Severn Waterway National Historic Site, helping ensure this historic canal corridor remains accessible for future generations.
