ORDNext – The New Concourse D

The New Concourse D is a key component of ORDNext, the ambitious curb-to-gate transformation of O’Hare International Airport into a modern, world-class global hub.

Designed to serve both international and domestic passengers, the 590,000-square-foot, multi-level concourse will enhance operational efficiency while improving the overall passenger experience at one of the nation’s busiest airports. A 225-foot, single-level connector will link Concourse D to Concourse C.

Adding 19 new gates built to the Multiple Aircraft Ramp System (MARS) standard, the project is engineered for flexibility, allowing it to accommodate a range of aircraft types. This adaptability optimizes airline operations and reduces the need for layover transfers, making connections smoother for travelers.

The concourse draws its design inspiration from Orchard Field, the airport’s original name. A tree-like structural system opens the interior into column-free, daylit spaces, reflecting Chicago’s architectural legacy while advancing the future of aviation infrastructure. Concourse D is designed by Skidmore, Owings & Merrill (SOM) in collaboration with Ross Barney Architects, Juan Gabriel Moreno Architects (JGMA) and Arup.

Supporting infrastructure improvements include a stormwater project that will facilitate the future elimination of a detention basin west of the concourse. This water management strategy redirects stormwater to an expanded basin on the southeast end of the airfield, ensuring sustainable and efficient site development.

Construction is being delivered by the AECOM Hunt Clayco Bowa joint venture and is expected to support more than 3,800 construction jobs. Completion is anticipated in late 2028.
