State Street Bridge Rehabilitation
This accelerated bridge project was a multi-phased agreement to rehabilitate an historic six span, concrete spandrel arch structure over the Schuylkill River. The 528-foot structure provides the only access from the west to the town of Hamburg, with average daily traffic of 12,000. In addition to performing an in-depth, hands-on inspection and loading testing, WBCM developed plans for the reconstruction of the deck and floor beam system. Existing cellular abutments were reconstructed by designing closure walls at the arch rib interface, removing the top slab, and in-filling the abutment cavity with lightweight fill. The 45-degree skew of substructures required attention to detail in developing the floor beam and deck details. The project was in a detailed Federal Emergency Management Agency study area and required permits under the National Pollutant Discharge Elimination System (NPDES) and Joint Permit Application (JPA) processes. Traffic was detoured during construction. Extensive public involvement was required to obtain buy-in from stakeholders and to ensure the closure adequately coordinated emergency response considerations. Turning lanes and a traffic signal were constructed for the Industrial Drive intersection west of the bridge.
