The NCC is investing in major upgrades to the Canadian Pacific Railway (CPR) Overhead Bridge on the Kichi Zībī Mīkan. The bridge needs important work to ensure it meets safety standards and functional requirements.
Built in 1966, the bridge is a key structural element of the Kichi Zībī Mīkan. It spans the Trillium Pathway where it meets the Capital Pathway, near the Chief William Commanda Bridge. This area serves as a vital link for pedestrians and cyclists travelling between Ottawa and Gatineau.
These investments will extend the bridge’s life by about 30 years. The work will bring it up to current safety standards and address key structural issues.
Scope of work
- Rehabilitating the bridge’s structural elements
- Rebuilding the deck overhang
- Replacing the bridge and approach guard rails
- Renewing catch basins for improved drainage
- Expanding joint conversions to semi‑integral ends
- Paving new road on the surface of the bridge
Project impacts
For motorists: Lane reductions over two construction seasons.
- June 2026 to November 2026: Closure of both eastbound lanes. Bidirectional traffic flow will be maintained through the previous westbound lanes.
- May 2027 to fall 2027: Closure of both westbound lanes. Bidirectional traffic flow will be maintained through the previous eastbound lanes.
For pedestrians and cyclists: The multi-use pathway beneath the bridge will remain open and accessible during construction. Weekend Bikedays will continue through the area, using a one-lane detour route.
Process and timeline

- Summer 2026: Rehabilitation of the eastbound portion
- Winter 2026–2027: Reopening of the bridge to limit traffic impacts
- Summer 2027: Rehabilitation of the westbound portion
