To ensure pedestrian safety through the SR 22/SR 145 Interchange project site in Allentown, PA., Benesch developed a conceptual temporary pedestrian structure and associated approach walkway. The pedestrian bridge’s main span is 115’ with a min. vertical underclearance over SR 22 of 16’-6”. The bridge clear walkway width of 8’ meets applicable ADA requirements. The $330,000 temporary bridge was comparable to the cost of adding extra width into the proposed replacement bridge.
