Assessment of the existing bridge: Perform an in-depth inspection of the bridge superstructure to include Ground Penetrating Radar (GPR) testing of the concrete deck, ultrasonic thickness measurements of the steel beams, and measurements of the bridge deck and steel beams adequate to perform load rating of the superstructure.
Phase 2:
1. Perform load rating of the superstructure to determine its load carrying capacity. The superstructure will be rated to meet HL-93 AASHTO loads.
