AOA Alert Closing of Post 11, Opening of New Post 11

Effective January 21st-23rd, 2020

Another incredible milestone at O'Hare. After a little over 25 years, post 11 that we have used to access the airfield from the east side, will be permanently closed and relocated.


This closure is the next step in the expansion of Terminal 5 and the "M" Concourse which is scheduled to start this spring and open in 2023.


The closing of existing post 11 and opening of the new one will take place between Tuesday, January 21 and Thursday, January 23. The exact date is not yet finalized as numerous inspections must be completed prior to the move.


Post 11 will be accessed from Balmoral Ave off of Bessie Coleman Drive NOTE: you cannot access new post 11 from the Mannheim fly over bridge going south.


As shown in the attached graphics, this entire area that has been landside for the past several months will now become airside. 


Please ensure vehicle operators know to follow all posted service road signs and NOT drive through the construction site.




Keep an eye out for construction workers near the new post 11.
