GeoMetrix was retained by the prime consultant for this major bridge rehabilitation over the Athabasca River. The existing bridge is a railway truss originally constructed in 1913 that was converted into a highway bridge in 1963 with the addition of precast concrete stringers. Due to deterioration the exterior stringers and barriers are being removed and replaced with wider precast panels to improve the roadways function standard. GeoMetrix performed the independent design check of all new superstructure components. This included checking the new precast panels for gravity loads and barrier impact loading as well as a review of the construction details such as dowels and keeper bars. GeoMetrix also performed a bridge load evaluation of the new panels, existing truss members, and existing bent members for the new wider configuration. This included permit vehicles, the revised design vehicle, and well as a number of owner superload vehicles.
