A major rehabilitation project on a key Fraser River crossing in British Columbia is underway, with construction expected to continue through summer 2029. The work will address structural deterioration and extend the service life of the historic Agassiz-Rosedale Bridge while keeping the transportation corridor open to the public.
The Agassiz-Rosedale Bridge carries Highway 9 across the Fraser River in the District of Kent. Its structure includes 11 south approach spans, six river spans, 25 north approach spans and 50 north viaduct spans.
The rehabilitation will address several components of the ageing bridge. Planned work includes replacing deck joints and bearings, encapsulating concrete approach expansion bent caps, and repairing and strengthening deteriorated steel truss members.
Crews will also install drain troughs beneath expansion finger joints, clean and recoat deteriorated steel, and remove existing lead-based coatings.
Graham's Infrastructure team, based out of its Vancouver Operations office, will deliver the project in collaboration with Seabird (Sq’éwqel) Island Band and Cheam First Nation.
The bridge will remain open throughout construction. Work will proceed in two half-width phases, with single-lane alternating traffic maintaining access across the Fraser River. Traffic management will be a central consideration during construction.
The Agassiz-Rosedale Bridge is an important transportation link for communities across the Fraser Valley. Addressing deterioration in its structural components will help maintain the crossing's long-term reliability and reduce the need for more extensive future repairs.
Keeping the bridge operational during construction will also help limit disruption for motorists and other corridor users. Construction has begun, with completion targeted for summer 2029.
