About this Project

This project aimed to rehabilitate Chestnut Street in the University City area, including the Chestnut Street Bridge over the Schuylkill River and several adjacent structures between 31st and 23rd Street in the City of Philadelphia, Pennsylvania. The Chestnut Street Bridge over the Schuylkill River was rehabilitated, repaired, and repainted, while the remaining bridges underwent deck replacements. Additional project components included the installation of new traffic signals, constructing of wider sidewalks, resurfacing, retaining wall rehabilitation, and re-striping pavement markings to add a bike lane.

AEG was involved with a variety of components for this project. Our structural engineers provided plans for the temporary excavation support and protection systems for multiple bridges. One bridge posed some difficulty. This bridge, spanning the CSX rail lines, was constructed with a historical arch that could not move during reconstruction. AEG took on the complex challenge of designing the temporary arch support used during the replacement of the bridge deck while trains traveled the active railroad below, ensuring the arch was retained in the process. AEG also provided structural calculations for multiple project components, including sidewalk demolitions, and performed surveys at various sites.
