From farmland to ‘global terminal’: A visual history of O’Hare International Airport

O’Hare International Airport is about to undergo the single largest, most expensive terminal revamp in its 73-year history. The $8.5 billion plan calls for a state-of-the-art global terminal, dozens of new gates and several additional concourses. It’s an effort to modernize an airport prone to delays that’s been struggling for decades to get ready for the 21st century.

Major changes have been a constant at O’Hare, from when construction equipment first tore up Orchard Place farmland to build a military aircraft assembly plant here in the early 1940s to the recent modernization plan’s East-West runways which have cleared the way for the new terminal work.
