Project Summary

The O’Hare Modernization Program (OMP) will reconfigure O’Hare International Airport’s intersecting runways into a more modern, parallel layout. The $6.6 billion Program will substantially reduce delays in all weather conditions and increase capacity at the airfield, allowing O’Hare to meet the region’s aviation needs well into the future.

The OMP will also bring a new western terminal facility with more airline gates and parking. The western terminal will be connected to O’Hare’s main terminal core by an automated people mover system.
