Schuylkill Avenue Viaduct Repairs Nearing Completion, Rehab Continues on South Side of Chestnut Street Bridge

Winter 2020-21 – PennDOT’s contractor continues repairs to structures over Interstate 76 on the west side of the river while rehabilitation of the Chestnut Street stone arch bridge over the CSX Railroad on the east side of the river has been delayed by unforeseen scheduling conflicts, delaying completion of the bridge over the Schuylkill River until fall 2021.

Rehabilitating, re-decking, and construction of new sidewalks on the Schuylkill Avenue West viaducts (see above) over Interstate 76 on the west side of the river between Market Street and Walnut Street continue as conditions permit over the winter and are expected to finish this spring.

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 began in mid-February. The trail will be closed for 90 days while the wall is repaired.  A detour will route pedestrian and cycling traffic around the closed section of trail during construction.

Rehabilitation of the viaduct under Chestnut Street that carries traffic between 30th Street and Schuylkill Avenue West is mostly completed. This viaduct carries Chestnut Street vehicular and pedestrian traffic over rail facilities at 30th Street Station.

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 will finish in the spring.

The concrete deck has been placed on the eastbound side of the bridge over the river, and crews this winter will complete installation of the eastbound sidewalk and parapets. Decorative lighting and parapet rails will be installed in the spring.

When finished and reopened, the rehabilitated Chestnut Street bridge over the river will have a new riding surface, new sidewalks, ornamental railings, a trellis entrance structure, decorative lighting, and a parking-protected bicycle lane.

As the large river bridge is rehabilitated, the contractor continues repairing the stone arch bridge over 24th Street (see below right). Repairs to the adjacent arch bridge over the CSX Railroad will extend through mid- 2021. The main bridge cannot reopen to vehicular traffic until both 150-year-old structures are modified to strengthen their arch supports and reconstruct their masonry components and decks.

Prior to the river bridge reopening in fall 2021, Chestnut Street will be milled and repaved between 22nd Street and 31st Street. 

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.
