Salt Lake Air Route Traffic Control Center

Salt Lake Air Route Traffic Control Center (ZLC) is a federal air traffic control facility established April 1, 1939, by the U.S. Department of Commerce's Bureau of Air Commerce. Located in Salt Lake City, Utah, it operates as part of the FAA's National Airspace System, managing en route air traffic control across a designated airspace region. The center evolved from the early federal air traffic control system that began in 1936 to improve aviation safety. ZLC remains an active operational facility providing critical air traffic management services for commercial and general aviation in the western United States.
