The FAA announced Thursday it would move ahead with the closure of control towers at the Columbus and Gary airports.
The FAA will begin shutting down 149 towers across the U.S., including those at the Gary/Chicago International Airport and Columbus Municipal Airport, on April 7. The process is expected to take four weeks.
The closures are part of the plan to meet upwards of $637 million in cuts.
The federal agency originally announced it would close 189 towers because of sequestration. However, it allowed airports to appeal. Those that demonstrated closing their towers would have a negative impact on the national interest are being allowed to stay open.
Congress passed a bill this week that keeps the federal government funded for the rest of the fiscal year. It alleviated some of the cuts from sequestration, but left the majority of them in place, including cuts to the FAA.
