The Pennsylvania Department of Transportation and the Federal Highway Administration are undertaking a long-term, multiphase project to improve and rebuild Interstate 95 (I-95) in Pennsylvania, within the historic city of Philadelphia. Given the complex urban setting, the archaeological subsurface testing for the I-95 Girard Avenue Interchange Improvement Project is being guided by a programmatic agreement under Section 106 of the National Historic Preservation Act and a categorical exclusion under the National Environmental Policy Act. Through data-recovery excavations, the contractor for the project, AECOM, has documented 30 historical-period and Native American archaeological sites. The project includes its own professional journal, live interactive reporting, and a public archaeology center.
