Wapiti River Bridge - Overall View of Existing Structure
The bridge on HWY 40 over Wapiti River, BF 74228, is comprised of four (4) lines of built-up steel plate girders spanning 33.5 m – 48.8 m – 61.6 m – 48.8 m – 33.5 m. GeoMetrix worked with the General Contractor, Ardy Rigging, to provide an engineered bridge jacking procedure and jacking drawings for lifting the girders which required a bearing reset or replacement. Procedures were also developed for the contractor to complete various Crack Induced Fracture (CIF) steel repairs including: crack repair of upper and lower longitudinal stiffeners, repair of gusset plate connections to girder web, and coring relief holes into web at intermediate and bearing stiffeners.
