About

The modernization project includes a Terminal Vertical Core (completed in 2022), which provides for vertical circulation of passengers with escalators and elevators, as well as connection to the APM’s West Central Terminal Area (CTA) station via an elevated pedestrian walkway over World Way. The Terminal Vertical Core will also connect to the reconstructed T4 Headhouse including new passenger check-in and baggage claim facilities, a consolidated security screening checkpoint.

A new south concourse will be constructed inside Terminal 4, featuring additional space for hold rooms, concessions, restrooms, and a bus gate that will serve both domestic and international traffic. Additionally, four of the refreshed gates will now be able to serve international traffic with expanded FIS secure circulation.

Additional work includes improvements to Terminal 4 power systems, including transformers and backup power, replacement of the terminal's aircraft apron and a reconfiguration of its hydrant fueling system and underground utilities.

In Terminal 5, the program added two gates to T5 making it a 15-gate terminal and added a new bus gate for transferring passengers between terminals. A new post security connection is being constructed to provide passengers connection between Terminals 4 and 5.
