In 1990, Bergstrom ended up on a list of 75 military facilities under study for closure by the post-Cold War Base Realignment and Closure Committee. On 30 September 1993, Bergstrom was officially closed and a bond was raised for Austin-Bergstrom International Airport. Much of the former air base, including buildings, trees, and structures, were completely demolished, with a few exceptions, such as the circular Twelfth Air Force Headquarters building (which was converted into a hotel) and the original 12,250-foot runway. Air cargo operations began in June 1997 and passenger operations started in May 1999.
