69828 | Market Street Bridges (3) Over Schuylkill River and CSX Railroad (MSB) (West Philadelphia & Center City Philadelphia)

This project involves the rehabilitation of the 2-span bridge carrying Market Street over the Schuylkill River , the replacement of the bridge carrying Market Street over the Schuylkill River Park and CSX railroad from a 4-span bridge to a 1-span bridge, and replacement of the 3-span Market Street bridge over I-76 at the Schuylkill Avenue West intersection in the City of Philadelphia.
The 2 span, 361'-long concrete encased steel arch bridge over the Schuylkill River was built in 1932 and is finished with limestone spandrel walls and fascia rings. Concrete urn-shaped balustrades and statues decorate the structure, although a quadrant of the balustrade has been filled with concrete. The bridge is significant as a contributing resource to the 30th Street Station Historic District. This bridge was previously determined eligible for listing in the National Register. The project includes the repairing and patching of the parapets and sidewalks as needed, replacement/repair of the deck and beams, and replacement of cobrahead lighting. The bridge is poor condition due to severe rust in in the substructure and spalling in the superstructure.
The 4 span, 216' long built up deck girder bridge over CSX railroad, built in 1932, is supported on concrete abutments and three steel pier bents, of which two are encased in concrete. This bridge was previously determined ineligible for listing in the National Register. This bridge will be replaced with a 1 span bridge with wider sidewalks.
The 3 span bridge over I-76 at the Schuylkill Avenue West intersection was built in 1932 and significantly modified in the late 1950s when I-76 was constructed. The bridge has significantly deteriorated and will be replaced.
Pedestrian and bicycle improvements are being coordinated with the City of Philadelphia throughout the project.
