Chicago O’Hare International Airport Begins $334 Million Runway Extension

Chicago’s O’Hare International Airport, one of the busiest aviation facilities in the world, broke ground Friday on the final piece of what will end up being a 16-year project to upgrade the airport.

City, state, federal and airport officials tossed the ceremonial first shovel-full of dirt to start the extension of O’Hare’s most-used runway, 9R/27L. The project will add 3,000 feet to the runway and will cost $334 million.

This part of the multi-pronged overhaul known as O’Hare Modernization Project (OMP) is expected to be completed in 2021. The project began in 2005 as a way to increase the airport’s ability to accept more frequent flights by long-haul aircraft.

Previous parts of the OMP realigned the airport’s runways into six parallel runways in an effort to reduce delays.

“We are very excited to begin the final phase of the O’Hare Modernization Project as we move forward with our full vision for O’Hare airport with the $8.5 billion O’Hare 21 program,” Chicago Mayor Lori Lightfoot in a statement. “Chicago’s status as a global city rests on O’Hare’s ability to handle the ever-increasing demand capacity, and today’s groundbreaking stands as a major milestone in ensuring a seamless experience for everyone passing through our city for years to come.”

The completion of the runway extension will set up the final phase of airport improvements, an ambitious $8 billion project that will create a 2.2 million-square-foot Global Terminal at O’Hare.
