Which taxiway is NOT used for general traffic at O'Hare Airport?

At O'Hare Airport, taxiways are designated for specific purposes, and each has a distinct function within the airport's operational layout. The taxiway identified in your answer is not designated for general traffic, meaning that it does not facilitate the typical movement of aircraft between runways and terminals, which is essential for regular airport operations.

TWY K is often allocated for specialized uses, which might include serving specific types of aircraft, ground operations, or maintenance activities rather than accommodating the general flow of air traffic. This specific designation helps ensure efficient and safe movement on the airfield while allowing the airport to manage various operational needs effectively.
