Attention Pilots and All Other O'Hare Airfield Users

On January 10, 2013 the following airfield changes at O’Hare International Airport occured:

  • Taxiway ZC becomes AA
  • Taxiway ZD becomes L1
  • Taxiway ZE becomes BB
  • Taxiway ZF becomes CC

New sections of airfield pavement south of Runway 10/28 have been built and are visible. These sections remain closed to operations while construction of the O’Hare Modernization Program (OMP) continues.

These name changes are the first step of an overall taxiway renaming implementation plan for O’Hare that will evolve over the course of the next 18 months and beyond to encompass the full construction of the O’Hare Modernization Program (OMP).

In order to accomplish these changes, a small group of taxiways will be re-designated every 56 days beginning January 10, 2013.
