Chestnut Street Bridges

PennDOT District 6-0 | Philadelphia County, PA


The purpose of this project is to rehabilitate Chestnut Street in the University City area, which includes the Chestnut Street Bridge over the Schuylkill River and nine adjacent structures between 31st and 23rd Street in the City of Philadelphia, Pennsylvania. The Chestnut Street Bridge over the Schuylkill River is being rehabilitated, repaired, and repainted, while the remaining bridges undergo deck replacements. Additional project components include installation of new traffic signals, construction of wider sidewalks, resurfacing, retaining wall rehabilitation, and re-striping pavement markings for the addition of a bike lane.

AEG, working with Buckley & Company, is involved with a variety of components for this project. Our structural engineers are providing plans for the temporary excavation support and protection systems for multiple bridges. One bridge in particular, poses some difficulty. This bridge, spanning the CSX rail lines, is constructed with a historical arch that cannot move during reconstruction. AEG took on the complex challenge of replacing the deck of the bridge while trains travel the active railroad below, being sure the arch is retained in the process. AEG is also providing structural calculations for multiple project components, including sidewalk demolitions; and surveying and design for 11 ADA-compliant concrete curb ramps throughout four intersections surrounding the bridges.

Construction is expected to be completed in late 2020.
