REPAIR OR REPLACEMENT EVALUATION: MANAYUNK BRIDGE, PENNSYLVANIA
The Manayunk Bridge, built by the former Pennsylvania Railroad circa 1918, is an important symbol of civic pride to the local residents. It was placed on the National Register of Historic Places on March 18, 1983. The mass concrete arch bridge has suffered extensive deterioration and has not been used for railroad service since the late 1980s. The structure has nine concrete spans, with a total length over 1,900 ft, across the Schuylkill River, Interstate 76, and two local roadways in the northwest area of Philadelphia. The owner commissioned an extensive study of the structure to determine if the bridge could be repaired or if total replacement was the only alternative. Through extensive site surveys, laboratory tests, computer analyses, and evaluation of alternatives, the technical consultants determined that the bridge could be economically rehabilitated.
