In the coming weeks, Parks Canada will begin a coordinated, multi-year infrastructure project along the Trent–Severn Waterway National Historic Site involving Peterborough Earth Dams and the Maria Street Swing Bridge.

The work 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.

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

Regular project updates are provided through a dedicated project webpage and an email subscription list. A public information session is planned for March, with more details (such as construction phases, timelines, and closures) to be shared shortly.
