Epstein-Engineered Recirculation Bridge Certified Green

The Epstein-engineered Recirculation Bridge at O'Hare Airport received a Green Airplane Certification from the Chicago Department of Aviation (CDA) for its sustainable design and construction.

The CDA credited this project for its "outstanding performance and lasting contributions to sustainable airport practices," as part of their Sustainable Airport Manual, a guidance to incorporate and track sustainability in administrative procedures, planning, design and construction, operations and maintenance, and concessions and tenants with minimal impact to project schedules or budgets.

For this project, Epstein was pleased to provide structural and civil engineering services for the Phase II bridge rehabilitation that spans over several roadway entrances at O’Hare. These areas included the elevated parking structure, the Hilton parking structure, and surface lots B and C. The bridge provides a continuous circulation access to the lower and upper roadways of Terminals 1, 2 and 3. It’s also connected to two loop ramps that provide circulation access to the EPS entrance as well as recirculation at the EPS exit back to the Terminals. Additionally, Epstein also provided lighting design and electrical engineering services for the parking booths, variable message boards, and roadway signage attached to the structure.

Based on the original condition of the existing bridge, a full replacement of the existing deck, superstructure, and substructure with a reuse of the existing abutment end supports was recommended. Epstein was selected and awarded this project through our Chicago Department of Aviation Task Order Service Request contract.

Thank you to the CDA for this recognition!
