Chestnut Street Bridges

Construction Update: Summer 2022

Downspout Installation, Arch Bridge Repairs Will Wrap Up Chestnut Street Bridges Project this Summer

July 13, 2022 – Work continues until mid-2022 to replace the stone facia on the south side of the 100-plus-year-old 24th Street arch bridge (see below) and the arch bridge over the CSX rail line in Center City Philadelphia. 24th Street will remain closed to through traffic until all of the work on the arch bridge and the surrounding area — new curbs and sidewalks, and paving under the bridge — is completed.

In addition, historic replica railings with granite pedestals are being installed following delivery this summer over the Chestnut Street structures over 24th Street and CSX.

Crews will finish installing downspouts, the final components of the viaduct’s new drainage systems, on the underside of the viaducts by mid-summer to wrap up construction on the two Schuylkill Avenue viaducts over Interstate 76.

At an adjacent location, the Chestnut Street Bridges contractor is making emergency repairs to two Verizon manhole vaults located under the eastbound travel lanes of the Market Street Bridge (see right). The work on the Market Street structure includes demolition, placement of re-bar, and cast-in-place concrete bridge deck replacement. The right lane on the bridge remains closed during these repairs, which are expected to take several months to complete.

The Chestnut Street Bridge over the Schuylkill River reopened to vehicles, cyclists, and pedestrians on March 19 (see below), re-establishing the eastbound connection between University City and Center City that had been closed for rehabilitation and repairs.

Prior to re-opening the river bridge and the adjoining section of Chestnut Street between the bridge and 23rd Street, crews completed reconstruction of the roadway and structural repairs on the separate stone arch bridges over the CSX rail line and over 24th Street.

Work on the Chestnut Street river bridge included repairs or replacement, and repainting of its structural steel components, construction of a new concrete deck, sidewalks, and parapets, and installation of new parapet rails and new decorative lighting.

Plus, new street lighting and new traffic signals — including a specialized “bicycle head” signal at Schuylkill Avenue and Chestnut Street — were installed along Chestnut Street between 31st Street and 23rd Street.

The project also made room for a parking-protected bicycle lane on the north side of Chestnut Street between 31st Street and 22nd Street (see below).

Repairs also have been substantially completed on two, adjacent viaducts carrying Schuylkill Avenue over Interstate 76 in front of 30th Street Station, on a subsurface viaduct carrying Chestnut Street over 30th Street rail facilities, and on-ramps to and from I-76 at Walnut Street.

New sidewalks were built on the viaducts, and clear acrylic barriers were installed atop parapets along the Amtrak Northeast Corridor tracks located on the west side of Schuylkill Avenue West between Chestnut Street and Walnut Street.

Repairs also were made 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 on the west side of the river.
