Modjeski and Masters Retained to Design New Passyunk Avenue Bridge

Modjeski and Masters was retained by the Pennsylvania Department of Transportation to design a replacement bridge for the existing Passyunk Avenue Bridge. The existing bascule bridge had been in service since 1911 but could no longer meet the demands of traffic in the area. We determined that a newer double-leaf bascule bridge would better serve the vehicular and marine traffic.
