Replacing an iconic link at the heart of the National Capital

The Alexandra Bridge has been a distinctive feature of the Ottawa–Gatineau skyline for over 120 years. The 575m-long, five-span steel truss bridge crosses between Kìwekì Point to the Canadian Museum of History.

Located on unceded, ancestral Algonquin territory, it forms part of a unique cultural, archaeological and landscape setting within a rich heritage context of high significance in the national capital city. Originally built for heavy rail, the bridge today provides almost 40% of pedestrian and cyclist crossings of the Kichi Zībī (the Algonquin name of the Ottawa River) however the iconic structure is reaching the end of its service life and its replacement is planned.

An Arup-led team with Knight Architects as Lead Bridge Architect was appointed in May 2023 as Technical Advisor to develop this unique project as part of an integrated project team with Public Services and Procurement Canada (PSPC) in partnership with the National Capital Commission (NCC). The role includes the conceptual design of the new bridge as well as procuring a Progressive Design Build partner and supporting engagement with the public, stakeholders and Indigenous communities.

In January 2025 the NCC Board of Directors granted an initial Federal Land Use, Design, and Transaction (FLUDTA) Approval for the preferred design concept, whose distinctive undulating arches are inspired by nature, particularly the native American Eel (Pimisi) and the dynamic, ever-changing movement of the river. This significant planning milestone paves the way for the further development of this new national landmark.
