Construction Update: Winter 2018-19

Bridge Repairs Continue on Schuylkill Avenue, Chestnut Street

January 2019 - Following a year of steady progress in 2018, work will continue through the winter months on the repair and rehabilitation of several bridges and viaducts along and adjacent to Chestnut Street between 23rd and 31st streets in Philadelphia.

Construction crews in early 2019  finished work on the east side of the Schuylkill Avenue viaduct over Interstate 76 between Chestnut and Walnut streets (above) and have shifted repair operations to the west side of the structure, where they will begin removing the existing concrete deck in mid-to-late winter.

Rehabilitation of the west side of the adjacent section of the Schuylkill Avenue viaduct in front of 30th Street Station and the IRS building between Market and Chestnut streets will continue into next spring. Crews there will continue cleaning and refurbishing the steel superstructure and pouring sections of the viaduct’s new concrete deck as conditions allow over the winter before making the shift to the opposite side next spring.

Nighttime lane closures will continue to be in place on I-76 during some of the Schuylkill Avenue viaduct repairs.

Crews also will continue working on repairs to two other structures on Chestnut Street on both sides of the Schuylkill River this winter.

Rehabilitation of the north side of viaduct that carries Chestnut Street over Lower 30th Street between 31st and 30th streets is expected to finish over the winter along with completion of the retaining wall and sidewalk on the north side of Chestnut Street. Operations to clean and refurbish the structure will move to the south side of Chestnut Street in the spring, a move that will require two lanes of traffic on Chestnut Street to shift the north side.

On the east side of the river, repairs continue on the south side of the Chestnut Street stone arch bridge over 24th Street.  With temporary arch supports in place on the underside of the structure (right), crews are replacing and re-pointing the field stones and arch stones on the southern face of the structure and reinforcing the arches that support the southern half of the 150 year old bridge.

Similar repairs to the northern half of the bridge and sidewalks are expected to begin next spring. The south sidewalk between 23rd and 24th streets will be replaced at the completion of repairs to the arch bridge on that side of Chestnut Street and after construction of two new precast concrete retaining walls on the south side prior to work shifting to the north side.

PennDOT’s contractor is gearing up to begin a major rehabilitation — including steel repairs, repainting and re-decking — of the main Chestnut Street bridge over the Schuylkill River (below) in mid-2019. The bridge will be closed and detoured for approximately one year to complete work on the multi-span structure.


Repairs to the stone arch structure over the CSX railroad between 24th Street and the Schuylkill River Trail are expected to get underway during work on the river bridge.

Repairs to strengthen the “river wall” (left) that helps support I-76 where it abuts the west side of the Schuylkill River beneath Schuylkill Avenue from Walnut Street to Chestnut Street also continue as conditions permit this winter.

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 next spring. Repairs to the ramp from westbound I-76 to 30th Street have been completed.

Repairs to a retaining wall at river’s edge that require closing of a section of the Schuylkill River Trail at Chestnut Street have been postponed until early January 2020. The trail will be closed 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.
