The rehabilitation of a key Fraser Valley transportation crossing is underway, with Graham Construction appointed to lead upgrades to the historic Agassiz-Rosedale Bridge in British Columbia. The project, awarded by the B.C. Ministry of Transportation and Transit, is intended to extend the service life of the Highway 9 crossing over the Fraser River in the District of Kent.
Built in 1956, the two-lane steel truss bridge spans approximately 1,870 metres. Its structure includes 11 south approach spans, six river spans, 25 north approach spans and 50 north viaduct spans.
The rehabilitation programme includes replacing 25 deck joints and 155 bearings, encapsulating concrete approach expansion bent caps, and repairing and strengthening deteriorated steel truss members. Drain troughs will also be installed beneath expansion finger joints.
Additional work involves cleaning and recoating deteriorated steel components and removing existing lead-based coatings.
The bridge will remain open to the travelling public throughout the construction period. Work will be completed in two half-width phases, with alternating single-lane traffic across the crossing.
This approach will require coordinated traffic management while crews carry out structural repairs over the Fraser River.
Graham's Infrastructure team, operating from its Vancouver office, will deliver the project in collaboration with Seabird (Sq’éwqel) Island Band and Cheam First Nation.
The rehabilitation is focused on maintaining the condition and service life of an established transportation link connecting communities across the Fraser Valley. Keeping the bridge operational during construction will also preserve access along Highway 9 while major structural components are upgraded.
Construction is underway, with the project scheduled for completion in summer 2029.
