Frankford Avenue crosses over the Pennypack Creek with a three-span, stone masonry arch bridge that has been a presence in the Holmesburg neighborhood of northeast Philadelphia for three centuries. Built circa 1697, the bridge is the oldest continuously-used roadway bridge in the United States and was suffering from severe deterioration and significant collision damage. When confronted with repair needs following a collision that destroyed a portion of a parapet wall, the Pennsylvania Department of Transportation opted instead for a full rehabilitation rather than a quick repair of the wall. PennDOT, in collaboration with TranSystems, developed a rehabilitation program for the bridge that addressed its structural deficiencies while maintaining its historic character, all while working with the local community, adjacent schools, SEPTA, Philadelphia Parks and Recreation and a consulting parties group (part of the Section 106 process) throughout the design and construction phases.
