George Wade and John Harris Bridge Inspections

Larson Design Group (LDG) performed a bridge safety inspection for PennDOT District 8 of the George Wade and John Harris Bridges in Dauphin County, Pennsylvania. The George Wade Bridge is over 5,200 feet long and the John Harris Bridge is over 3,300 feet long. Both bridges are more than 100 feet wide. LDG completed a hands-on inspection of the fracture-critical structures to meet the National Bridge Inspection Standards, verifying the bridges’ safety, and identifying any new problems since the last inspection was performed. The inspection took several weeks and multiple inspection crews. The structures were inspected using UB-60 and UB-75 under-bridge cranes, bridge trackers positioned in the river below the bridge, and two man-lifts for the spans over Norfolk Southern Railroad tracks. The amount of inspection time per day was limited to minimize disruptions to traffic using the bridges.
