Chicago's $1.3B O'Hare Expansion Creates 3,800 Jobs

Chicago is building big, and thousands of workers are clocking in to prove it.

O'Hare International Airport's new Concourse D just entered its most exciting phase this spring. After months of underground foundation work, cranes are now lifting steel columns skyward as part of a $1.3 billion transformation that's employing 3,800 construction workers across the city.

"With the improvements we are making at Concourse D alone we are generating more than 3,800 construction jobs that creates a ripple effect across Chicago's entire community," Mayor Brandon Johnson said at the groundbreaking last August. It's the first major concourse built at O'Hare in more than three decades.

The new structure will add 19 gates designed for flexibility. Eighteen of those gates can adapt to handle either narrow-body jets for domestic flights or convert into nine larger ports for wide-body international aircraft.

Designers drew inspiration from O'Hare's original name, Orchard Field, honoring the apple orchard that once stood on the site. That history comes alive through dramatic tree-like columns that branch outward to support a 150-foot-wide roof, cutting interior columns by nearly half and opening up the space for easier passenger flow.

The concourse will include over 20,000 square feet of lounge space, 30,000 square feet of shops and restaurants, and a 450-square-foot play area for traveling families. Completion is scheduled for late 2028.

The Ripple Effect

This project represents just the opening act of ORD21, Chicago's $8.5 billion vision to reimagine O'Hare for the next century. Additional phases include replacing Terminal 2 with a new O'Hare Global Terminal and constructing Concourse E with 24 additional gates.

The timing couldn't be better. O'Hare saw over 8 million passengers last June, the highest June total in its 70-year history and the second-busiest month ever recorded.

"Airport planning is not for the next year, it's for the next generation," said Chicago Department of Aviation Commissioner Michael McMurray. "If you're not planning ahead then you are falling behind the curve."

When the full expansion wraps up, O'Hare will have 14 percent more gate capacity and dramatically improved flexibility for hub carriers United Airlines and American Airlines. For the 3,800 workers building it today, that future is taking shape one steel beam at a time.
