Federal officials Friday released a list of 149 contract towers that will be impacted by the spending cuts. The list includes the Dothan Regional Airport and the Tuscaloosa Regional Airport.

The Northwest Alabama Regional Airport in Muscle Shoals and Pryor Field next to Calhoun Community College will not be affected. Those two airports do not have an air traffic control towers.

In a statement, American Association of Airport Executives and U.S. Contract Tower Association representatives say the closures raise safety, efficiency and economic concerns federal officials have failed to consider.

Federal officials say the closures are being implemented to meet a $637 million budget cut.

FAA officials say the closures are scheduled to begin April 7 and will be executed over the course of four weeks.
