The project consists of the proposed replacement of the Crum Creek Viaduct over Crum Creek in Swarthmore Borough and Nether Providence Township, Delaware County. The existing viaduct is approximately 900 feet long, with seventeen spans, approximately 100 feet high, and was constructed in ca. 1897. It is currently used by SEPTA’s Media/Elwyn Line commuter railroad line. Because of the length and height of the viaduct and the fact that it carries an active rail line, the proposed project will involve extensive preparation time and will necessitate several access points and staging areas for large materials and equipment.
ASC Group is conducting wetlands delineation, bog turtle investigations, and coordination with state agencies regarding threatened and endangered species that may be affected by the project.
ASC Group is also completing a Phase I Archaeological Study in the project staging areas and close to Crum Creek. This included field investigations, shovel tests, test unit research, and site identification in the affected areas.
ASC Group will be documenting three historic resources on Pennsylvania Historic Resource Survey Forms and evaluating their potential eligibility for listing in the National Register of Historic Places. Those resources include Swarthmore College, the ca. 1897 Crum Creek Viaduct, and the 1927 Crumledge Farm designed by R.B. Okie.
