Chestnut Street Bridge Rehab Continues

Section of Schuylkill River Trail to close this winter for repairs

Winter 2019/2020 - Construction this winter will continue the rehabilitation of several bridges and viaducts in Center City Philadelphia, including the Chestnut Street Bridge over the Schuylkill River, the stone arch bridge over 24th Street, and the Schuylkill Avenue viaducts over Interstate 76.

Crews have been rehabilitating the steel components on the north side of the bridge over the river between 24th and 30th streets since early fall while Chestnut Street is being reconstructed between 23rd Street and the river bridge. A containment system has been installed to prevent dust from getting into the air/water during abrasive blasting and painting of the structural steel members that support the bridge.

When the road reconstruction between 23rd Street and the river bridge finishes this winter, work will get underway on the southern half of the river bridge, closing the span completely to motorists, bicyclists and pedestrians at that time.  Crews will then remove the remaining sections of the concrete deck from the southern half of the bridge and begin refurbishing the steel girders and other structural members on that side.

Scheduled for completion in late summer 2020, the rehabilitated Chestnut Street Bridge over the river will have a new riding surface, new sidewalks, ornamental railings, a trellis structure, decorative lighting and bicycle lanes in both directions.

As the large river bridge is rehabilitated, the contractor continues repairing the stone arch bridge over 24th Street. The 150 year-old bridge is being modified to strengthen its arch supports and reconstruct their masonry components.

Repairs to a retaining wall at 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 will be done over the winter. The trail will be closed for 90 days while the wall is repaired. Work here is expected to finish and the trail reopened to the public in April. A detour will route pedestrian and cycling traffic around the closed section of the trail during construction.

On the west side of the river, rehabilitation of the Schuylkill Avenue viaducts over Interstate 76 between Market and Walnut streets continues to progress. Crews have replaced most of the concrete deck on the Schuylkill Avenue viaduct between Chestnut and Walnut streets and are now replacing concrete sidewalks and parapets and applying the final paint coat to the underlying structural steel support members. Structural repairs and re-decking are now underway on the west side of the viaduct between Chestnut and Market streets.

The ramps from Walnut Street to I-76 east and from westbound I-76 to 30th Street have been repaired, including replacement of the expansion dams and new pavement surface overlays.

Rehabilitation is also now underway on the south side of the viaduct that carries Chestnut Street over Lower 30th Street between 31st and 30th. Similar repairs on the north side of Chestnut Street at this location finished over the summer. Two lanes of Chestnut Street traffic have been shifted to the north side. Work will take place in late winter or early spring to complete repairs on the south side of Chestnut Street.

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 continuing.

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.
