About this Project

This work involves preliminary engineering, final design, and construction services for the proposed reconstruction of the Byberry Road Bridge in Philadelphia, Pennsylvania. The project is located across CSX’s railroad tracks just north of the US Route 1 and State Route 63 interchange in the City of Philadelphia.

The bridge is situated in bedrock from the Wissahickon Formation, a well-known schist rock often highly weathered to a moderate depth. The weathering results in a hard-to-define bedrock surface, typically associated with poor recovery and very broken bedrock.

AEG is responsible for Preliminary Geotechnical Engineering Report (PGER) Studies for the bridge, approach roadway, and two retaining walls along the western side of the proposed bridge structure; coordination and oversight of the drilling program, including preparation of the Subsurface Exploration Plan and Boring Contract; full-time field oversight of the borings by PennDOT- certified drilling inspectors; soils and rock laboratory testing; and preparation of plotted logs. AEG prepared foundation recommendations and submitted a Final Structure Foundation Report for the structure replacement. In addition, AEG will provide consultation as needed during the construction phase of this project.

The CSX railroad remains an active railroad for this assignment.
