CN Bridge Rehabilitation program overview
Since 2017, Canadian National Railway (CN) has completed rehabilitation and repairs on several cost-shared structures within the municipality, as listed below. Future plans for further rehabilitation work in partnership with the municipality are underway. This work includes:
- Rehabilitation to the arch bridge structures (responsibility of CN); and
- Full replacement of the paved surface and sidewalk(s) at each location (responsibility of the municipality).
Tower Road CN Bridge Rehabilitation project
In collaboration with the Halifax Regional Municipality, Halifax Water and other partners, CN is leading the Tower Road CN Bridge Rehabilitation project, a necessary infrastructure improvement to ensure long-term safety and reliability.
This work is part of a multi-year plan to rehabilitate seven CN bridges on the Halifax peninsula. With five bridges completed, the Tower Road bridge is the sixth project.
Project status and timeline
The Tower Road CN Bridge Rehabilitation project has been tendered, and the contract will be awarded to the selected contractor in the coming weeks.
Construction is tentatively expected to begin no earlier than the week of May 5, 2025, with work continuing into December 2025 before pausing for the winter season and resuming in spring 2026. This project is expected to be completed in spring/summer 2026.
The municipality will provide project updates and related traffic impacts through halifax.ca/news, social media, and direct community outreach.
What can I expect when construction starts?
The municipality is working in partnership with CN, Halifax Water and other involved utilities to coordinate construction activities and minimize impacts where possible.
To ensure the safety of road users and construction crews, the Tower Road CN bridge will be closed to all users (including pedestrian/cycling use) until December 2025. A marked detour will be in place via the Young Avenue CN bridge.
CN and the municipality expect to temporarily reopen the Tower Road CN bridge to all road users beginning in December 2025 until work resumes in spring 2026 for the final phase of the project. A status update on this expected approach will be communicated in fall/winter 2025.
Halifax Transit routes will detour around this work. When updates are available, they’ll be posted on halifax.ca/htdisruptions.
Common questions
- Will any trees be removed as part of this project?
CN has hired an arborist to remove trees from CN property that will obstruct the Tower Road CN Bridge Rehabilitation project.
This work will be completed by April 1 to avoid the potential for nesting activity. This work does not involve any trees off CN property.
