St. Louis Regional Airport
The towers are all operated for the FAA at low-traffic airports and were to close by mid-June as the result of government-wide automatic spending cuts imposed by Congress.
The original list of threatened towers contained 189 contract towers but the Administration was able to stave off the closure of 40 of those, leaving a final list of 149.
The Federal Aviation Administration said in a letter, any review of proposed cuts would only be based on national interests.
St. Louis Regional Airport would remain open after April 1, but without air traffic controllers, thanks to FAA budget cuts.
Airfield in Bethalto, Ill. is on list of those at risk of losing FAA control tower funding.
