Construction Update: Fall 2021

Work Continues on Chestnut Street Arch Bridges, Chestnut Street to Reopen in 2022

October 21, 2021 – With the repair and rehabilitation of two viaducts over Interstate 76 substantially completed, topside work on two adjacent Chestnut Street stone arch bridges (see below) on the east side of the river is headed for completion that will allow Chestnut Street to reopen to vehicles, pedestrians and bicyclists between Schuylkill Avenue on the west side and 23rd Street on the east side in early 2022.

On the stone arch spans, crews have removed and replaced the original facia stones on the north side of the bridges and are completing repairs to strengthen the arch barrels on the structures over a Norfolk Central rail line and 24th Street and complete the reconstruction of Chestnut Street between 24th and 23rd streets.

Work on the south side facia of the 24th Street arch will continue into mid-2022 without impacting Chestnut Street traffic. 24th Street will remain closed to through traffic under Chestnut Street until all of the bridge work is completed.

The contractor also has rehabilitated the Chestnut Street river bridge’s structural components, placed a new concrete deck and sidewalks, installed the new parapet rails, and new decorative lighting. A protected bicycle lane on the north side of the river bridge will be installed in advance of the bridge reopening.

Repairs to a retaining wall supporting the Trail against the eastern bank of the river under Chestnut Street have been completed and the trail was reopened in July following a month-long closure to complete the work.

Topside work to repair and rehabilitate two adjacent viaducts carrying Schuylkill Avenue over Interstate 76 on the west side of the river also finished in late summer. The viaduct's 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 (see left) on the separate viaduct structures between Market and Chestnut streets, and between Chestnut and Walnut streets. Protective shielding and new lighting on the underside of these viaducts will be installed this summer to complete improvements to the structures.

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.

Most of the repairs to strengthen the “river wall” (see above) that helps support I-76 where it abuts the west side of the Schuylkill River beneath Schuylkill Avenue from Walnut Street to Chestnut Street have been completed.

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.
