The Chicago Department of Aviation (CDA) this week announced the opening of all seven renovated pedestrian tunnels beneath the Lower Level Roadway at O’Hare International Airport (ORD) as part of efforts to improve the overall passenger experience at one of the world’s busiest airports.

Crews used 3D laser scans of the tunnels to facilitate the repairs, which were conducted in conjunction with interior renovation work. The new designs, inspired by Chicago’s vibrant history and commitment to sustainability, feature wood finishes and asymmetrical curved metal wall and ceiling panels.

Each tunnel features its own distinct floor finish pattern and large LED screens displaying vibrant scenes of the city, important travel information, and can be used to broadcast emergency notices if needed.

“These new tunnels provide a more vibrant and inviting welcome to Chicago for travelers connecting between the Terminals and the CTA Blue Line station, O’Hare’s Elevated Parking Structure, or the Hilton Chicago O’Hare Airport Hotel,” said Jamie Rhee, CDA commissioner.
