January 2018 - Stage 1 construction continues this winter on the rehabilitation of two sections of the Schuylkill Avenue viaduct over Interstate 76 near 30th Street in Center City, on the viaduct that carries Chestnut Street over Amtrak lines between 30th Street and Schuylkill Avenue, and on a section of the stone arch bridge carrying Chestnut Street over 24th Street.
The work is part of PennDOT’s $103.6 million project to rehabilitate of the Chestnut Street Bridge over the Schuylkill River and seven adjacent or nearby structures. Construction began in August 2017 and is scheduled to be finished in late 2020.
Crews completed installation of protective shielding on the underside of the Schuylkill Avenue viaducts over I-76 between Market and Walnut streets in December. With shielding in place, they removed the concrete deck and began repairs to the steel superstructure on northbound Schuylkill Avenue over I-76 between Walnut and Chestnut streets and on southbound Schuylkill Avenue over I-76 between Market and Chestnut streets.
Those two sections of Schuylkill Avenue remain closed to traffic. Occasional nighttime lane restrictions and closures will be continue to be in place on I-76 during some of the viaduct repairs.
Construction also continues beneath Chestnut Street between 31st and 30th streets. With this one-block stretch on the north side Chestnut Street closed to vehicles and pedestrians, crews will install shoring, excavate the pavement and subgrade materials, and begin rehabilitation of the viaduct over 30th Street.
Crews also will rehabilitate the existing concrete retaining wall located along the north side of Chestnut Street.
After installing ADA (Americans with Disbilities Act) curb ramps at the corners of 23rd and Chestnut streets, the contractor in December closed the south side of Chestnut Street — including the sidewalk — from the eastern end of the bridge over the Schuylkill River to 23rd Street and started repairs to the stone arch Chestnut Street bridge over 24th Street.
24th Street is closed to vehicles and pedestrians beneath Chestnut Street.
Additional Stage 1A work will continue through mid-2018. Go here for details.
