Construction Update: Summer 2019

Chestnut Street Bridge Closed  for Rehabilitation

August 2019 – The Chestnut Street Bridge over the Schuylkill River closed in early August for approximately one year for rehabilitation and repainting of the bridge's structural steel components and for placement of a new concrete deck.

The rehabilitated span, which crosses the Schuylkill River between 24th and 30th streets, also will include new sidewalks, ornamental railings, a trellis structure, decorative lighting, and bicycle lanes when it reopens in mid-summer 2020.

Debris shield in place under the Chestnut Street BridgeCrews have completed placement of the debris shield/work platform on the underside of the bridge. A containment system is being installed to prevent dust from getting into the air/water during abrasive blasting and painting of the structural steel members that support the bridge.

During work on the river bridge, Chestnut Street also is closed to through traffic between 23rd and 24th streets - it will remain open to local traffic and emergency vehicles which will be permitted to enter from 23rd Street and travel west to buildings on the closed block.

The arch bridge under Chestnut StreetAs the large river bridge is rehabilitated, the contractor also will continue repairs to the stone arch bridges over CSX rail lines on the east bank of the river and over 24th Street. Both 150-year-old bridges are being modified to strengthen their arch supports and reconstruct their masonry components.

On the west side of the river, rehabilitation of the Schuylkill Avenue viaducts over Interstate 76 between Marker and Walnut streets continues to progress. 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.

Placing the concrete deck on the Schuylkill Avenue viaduct

On the west side of the viaduct between Chestnut and Market streets, 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.

Structural repairs, including replacement of the expansion dams, have been completed, and new pavement surface overlays have been placed on the ramps from Walnut Street to I-76 east and from westbound I-76 to 30th Street.

Rehabilitation of the north side of the viaduct that carries Chestnut Street over Lower 30th Street between 31st and 30th streets finished in early summer, 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 have been moved to the south side of Chestnut Street, requiring two lanes of traffic on Chestnut Street to be shifted to the north side.

The "river wall" under I-76

Repairs to strengthen the "river wall" that helps support I-76 where it abuts the west side of the Schuylkill River beneath Schuylkill Avenue from Walnut Street to Chestnut Street are ongoing.

Repairs to a retaining wall at the River's edge on the east side of the river under the Chestnut Street Bridge that require closing 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 structures. Construction began in August 2017 and is scheduled to finish in late 2020.
