Spring 2019 - As rehabilitation of the Schuylkill Avenue viaducts over Interstate 76 continues along with repairs to several other structures on and adjacent to Chestnut Street, preparations are underway this spring for a year-long shutdown beginning in mid-July for major repairs to the bridge over the Schuylkill River.
Crews are installing the under-side shielding (above) that will serve as a work platform and prevent construction debris from falling into the river during construction to repair and rehabilitate the Chestnut Street Bridge. The structure spans the river between 24th Street on the east side and the Schuylkill Avenue viaduct on the west side.
The bridge is expected to be closed to all vehicular and pedestrian traffic in mid-July for steel repairs, repainting and re-decking.
Structural repairs, including replacement of the expansion dams, are completed on the ramp from Walnut Street to I-76 east. The ramp’s latex concrete pavement overlay, similar to the one used on the westbound I-76 ramp, will be placed in late spring during a month-long closure of the ramp which is tentatively scheduled to begin the week of May 20. Repairs to the ramp from westbound I-76 to 30th Street have been completed.
Construction crews have replaced the deck on the east side of the Schuylkill Avenue viaduct between Chestnut and Walnut streets and are now repairing the opposite side of the structure. The old concrete deck was removed in early spring and ironworkers are repairing or replacing exposed structural girders and other structural components after they are sand-blasted clean.
On the west side of the viaduct between Chestnut and Market streets (below), the final segments of new concrete pavement will be placed this summer. Work will then begin on similar repairs on the east side of the viaduct.
Nighttime lane closures continue on I-76 during repairs to this viaduct.
Rehabilitation of the north side of the viaduct that carries Chestnut Street over Lower 30th Street between 31st and 30th streets will finish later this spring along with completion of the retaining wall and sidewalk on the north side of Chestnut Street and installation of a new water main. Operations to clean and refurbish the structure will then move to the south side of Chestnut Street, a move that will require two lanes of traffic on Chestnut Street to shift to the north side.
On the east side of the river, the Chestnut Street stone arch bridges over 24th Street and on the over the CSX rail line adjacent to the Schuylkill River Trail (left) remain in various states of repair.
Repairs also continue to strengthen the “river wall” (below) that helps support I-76 where it abuts the west side of the Schuylkill River beneath Schuylkill Avenue from Walnut Street to Chestnut Street.
Repairs to another retaining wall, at river’s edge beside the Schuylkill River Trail at Chestnut Street, will require closing the Trail at Chestnut Street in early January 2020 for 90 days while the wall is repaired.
The work is part of PennDOT’s $103.6 million project to rehabilitate 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.
