About this Project

This $96.5 million project, known as Section BR2, is part of PennDOT’s multi-phase initiative to reconstruct and modernize the Betsy Ross Bridge Interchange in Northeast Philadelphia. The work included the removal and replacement of seven bridges and two retaining walls, enhancing connections between the Betsy Ross Bridge, Aramingo Avenue, and I-95. Improvements also included new long-life concrete and warm mix asphalt pavement sections, drainage upgrades, guiderail replacements, highway lighting, and asphalt overlays extending onto the bridge.

AEG provided structural design, geotechnical engineering, and construction-phase surveying services. Responsibilities included structural calculations for multiple temporary excavation support systems used during ramp replacements. AEG designed a temporary tower supported on a geofabric-reinforced lightweight aggregate platform to support the I-95 ramp during staged construction. This innovative solution offered a more economical and constructible alternative to the previously proposed pile-supported platform. AEG’s work helped maintain traffic flow and minimize detours in a densely populated urban corridor with active rail and transit operations.
