Construction Update: Summer 2021

Schuylkill Avenue Viaduct Repairs Finish, Work Continues on Chestnut Street Arches

July 12, 2021– PennDOT’s contractor has substantially completed the repair and rehabilitation of two viaducts over Interstate 76 and repaired a section of the Schuylkill River Trail while work continues this summer and on two adjacent Chestnut Street stone arch bridges on the east side of the river prior to the full reopening of Chestnut Street across the river later this year.

The contractor has rehabilitated the Chestnut Street river bridge’s structural components, placed a new concrete deck and sidewalks, installed the new parapet rails, and begun installation of the bridge’s new decorative light posts.

On the stone-arch spans (see right), crews have removed the original facia stones — charting each for re-setting in its original location — and are strengthening the arch barrels on the structures prior to replacing the stones. The main bridge will reopen to vehicular traffic when work on both 160-year-old structures finishes.

Repairs to a retaining wall supporting the Trail against the eastern bank of the river under Chestnut Street also wrapped up and the Trail reopened on July 2 (see below).

Work also has been substantially completed on the repair and rehabilitation of two adjacent viaducts carrying Schuylkill Avenue over Interstate 76 on the west side of the river. The viaducts’ structural components were repaired or replaced prior to re-decking, work that was done in stages in order to minimize travel impacts in the busy area adjacent to 30th Street Station.

New sidewalks, decorative parapets and lighting also were installed on the separate viaduct structures between Market and Chestnut streets, and between Chestnut and Walnut streets. 

I-76 on- and off-ramps at 30th Street also were repaired and resurfaced as part of the project, as was a separate viaduct carrying Chestnut Street over the 30th Street Station facilities.

Construction-related lane closures on Chestnut Street west of the river and travel restrictions on the Schuylkill Avenue viaduct also were lifted in early July.

Repairs to strengthen the “river wall” (see 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 are expected to finish this summer as well.

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