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
This project is being led by CN in collaboration with the Halifax Regional Municipality, Halifax Water and other partners. It is part of a long-term plan to improve safety and reliability by rehabilitating seven CN-owned bridges on the Halifax peninsula. Five bridges have already been completed. The Tower Road bridge is the sixth project in this multi-year effort.
Project status and timeline
As communicated in December 2025, the Tower Road CN Bridge Rehabilitation project began in early January 2026. With the temporary water main now installed across the Young Avenue CN bridge, rehabilitation work on the Tower Road CN bridge is ready to proceed.
To safely enable this work, the Tower Road CN bridge will be closed for all use, including drivers, cyclists and pedestrians, as of Wednesday, Feb. 4, and will remain closed until December 2026 when rehabilitation work is expected to be complete. A marked detour via the Young Avenue CN bridge will be in place while this work is underway.
What to expect during construction
The municipality is working with CN, Halifax Water and other involved utilities to coordinate construction activities and minimize impacts where possible. The bridge rehabilitation work is being completed by J Mason Contracting Limited on behalf of CN. The same contractor will also be completing the municipal and Halifax Water portions of this project, including paving the road surface across the bridge when the rehabilitation work has progressed to that stage of the project.
Project updates
The municipality will provide related significant traffic impacts through halifax.ca/news, social media and direct community outreach. 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.
