Arup is leading the technical advisor team supporting the further refinement of the preferred design for the Alexandra Bridge in Canada.
Following extensive consultation with indigenous communities, the public, stakeholders and advice from expert panels, the Canadian government’s National Capital Commission (NCC) board of directors has granted an initial Federal Land Use and Design Approval for the preferred concept design for the replacement of the Alexandra Bridge.
Linking Ottawa and Gatineau, the new bridge will serve as a model for sustainability and play its part in connecting current and future generations. This significant milestone paves the way for the further development of this new national landmark.
The preferred concept, ‘Motion’ is an arch bridge inspired by nature and particularly the eel, a native species of the Kīchī Zībī (the Algonquin name of the Ottawa River). Three pairs of arches rise and fall over the river, offering interest both above and below. The structure will support road and active modes of travel, with separated lanes for vehicles, cyclists, and pedestrians, ensuring a safe and enjoyable user experience.
Advisor team, which is now supporting the further refinement of the preferred design as the project moves through the procurement processes. “The new bridge is inspired by the past and designed for the future. Its design responds to the challenge of both becoming an enduring landmark while recognizing and respecting Indigenous and other communities who have inhabited the land,” said Doug Balmer, Principal and Project Director at Arup.
Recognizing that the new bridge must function as a dynamic public space as well as an interprovincial transport connection, the design concept includes dedicated areas for recreation and sightseeing, resting, and a gathering place for special celebratory times. Extra space is given for accessible viewing platforms on the upstream edge, providing places to pause and enjoy views of the spectacular landscape and the architectural heritage of the city’s national symbols.
The integrated project team, composed of Public Services and Procurement Canada (PSPC), the NCC, and the Technical Advisor team led by Arup will work together to refine the preferred design concept and advance the progressive design-build procurement process. The integrated project team will also continue to engage with the public, Indigenous communities, and other stakeholders. As a next step, the team will develop a reference design.
Replacement of Alexandra Bridge will create a sustainable interprovincial transportation connection that prioritizes active mobility and highlights the symbolic importance of the site to all Canadians for generations to come.
