The tower is one of 149 A-T-C's to be shuddered as part of the agencies sequestration implementation plan. The F-A-A had proposed closing 189 towers to meet the $637 million in cuts required under the budget sequestration.
The Bloomington-Normal Airport Authority says CIRA's tower shouldn't be on that list because of its daily operations and connection to larger airports in the area.
Since then, they've started looking into other ways of keeping the tower open. They say a complete plan isn't in place, but will be finalized and announced soon.
Transportation secretary Ray LaHood says the agency heard from communities across the country about the importance of their towers and these were very difficult decisions.
The closures will not force the shutdown of any airports, but pilots will be left to coordinate take-offs and landings.
The F-A-A will begin a four week phased closure of the towers on April 7th.
