O'Hare Airport Work Receives Award of Merit

AECOM Hunt Clayco Bowa Win

ENR Midwest's 2025 Best Projects were announced, and our partnership AECOM Hunt Clayco Bowa made the list for the O’Hare 21 Terminal 5 landside parking project.

The project was delivered fast and efficiently without disturbing the traveling public. Some of the key features are a real‑time parking guidance system and 48 complimentary electric vehicle charging stations in a six-level, cast-in-place, post‑tension parking structure with two helical ramps, supporting more than 1,700 vehicles and two vehicular bridges, expanded curbside access, and modifications to the I‑90 on‑ramp to streamline passenger flow.

Thank you to our entire team and partners for bringing this project to life. O'Hare is one of the world's busiest airports, and this makes a big difference for travelers.
