Attention Pilots and All Other Airfield Users:

On July 19, 2018 the airfield changes listed below are scheduled to occur at O’Hare International Airport. These taxiway name changes support of continued construction of the O’Hare Modernization Program (OMP), and more specifically, to prepare the airfield for new Runway 9C/27C that is on target to be commissioned on November 5, 2020 and a new Central Deicing Pad scheduled to be opened in December 2018.

In addition, the following taxiway name changes will also occur:

  • Taxiway U becomes D
  • Taxiway U1 becomes D1
  • Taxiway TT extends south to connect to Runway 9R/27L
  • New Taxiway PP2 is published
  • Taxiway R2 becomes J
  • Taxiway R1 becomes T6
  • Taxiway K extends west to connect to Taxiway AA
  • New Taxiway K1 is published (but remains closed)
  • Taxiway L2 becomes K2
  • Taxiway L3 becomes K3

The Chicago Department of Aviation (CDA) has developed a "pilot awareness" flier/poster that details the upcoming airfield changes.
