110314 | 30th Street Viaduct over 30th Street Lower (Bridge) (Philadelphia City)

The purpose of the project is to rehabilitate the 30th Street Viaduct over 30th Street Lower between Market Street and Walnut Street to extend the useful life of the bridge. Work is planned to include deck replacement, superstructure and substructure cleaning & repair, and possible further rehabilitation. The underside of the bridge superstructure will be cleaned and repainted, with steel repairs as necessary. The bridge's drainage system will also be replaced and upgraded as needed. Recent bridge repairs have revealed accelerated deterioration of the structure, which will continue to worsen without rehabilitation, and could result in eventual weight restrictions or closure. Recent high-density development in the area has increased use of the viaduct, and pending future developments in the 30th Street Station area will further increase its importance, making future restrictions or closures highly disruptive.
A final alternative for bridge rehabilitation or replacement is determined upon federal National Environmental Policy Act (NEPA) or state Categorical Exclusion clearance.
