Additional renderings have been revealed as part of a new fly-through video of the upcoming Concourse D at O’Hare International Airport. The new concourse marks the first major expansion at the airport since the Terminal 5 expansion was completed in 2023. It is also the first phase of the overall ORDNext project and is expected to be completed in 2028.

Concourse D will sit southwest of the existing Concourse C and will be connected via an elevated tunnel. The tunnel will lead to the concourse’s anchor, The Orchard. This large circular space will hold 30,000 square feet of lounge space, along with restaurants, bars, retail, and seating areas, drawing inspiration from the airport’s history and its original name, Orchard Field.

The 580,000-square-foot structure will contain 19 new gates, which can be configured in multiple ways to serve aircraft of various sizes, including widebodies for long-haul service. The concourse will also be able to handle international arrivals, featuring a suspended sterile corridor that will guide passengers to a new passport control center to be completed later as part of the overall project.

The structure will feature 40-foot-tall ceilings supported by branching columns meant to mimic the aforementioned orchard. The concourse will be capped on the south end by a large wall of windows framing views of the city to the east. Eventually, the concourse will also be connected to the new Global Terminal and Concourse E via an underground tunnel.

ORDNext will add 14 percent more gate capacity at a crucial point in the airport’s history, as O’Hare recently reclaimed the title of the nation’s busiest airport by aircraft movements, with 857,300 total in 2025. This expansion also comes as United and American turn up the heat in their battle for the airport, with both airlines recently purchasing gates from Spirit.

Construction began in early 2025 with site work, underground utilities, and tunneling for the building. Vertical construction is expected to begin soon, with equipment already on-site. Additionally, O’Hare is set to award the largest concessions contract in the nation this March, which will include 110 commercial locations in Terminals 1 and 3.
