The Airway Radio Station in Gallatin County, Montana was built by the Aeronautics Bureau of the U.S. Department of Commerce in 1933. Located on Pogreba Field at Three Forks Airport, the radio station was part of a series of federally-constructed airway stations built during the early years of U.S. civil aviation. The station housed the radio range and ground-to-air radio systems that aided airmail pilots flying on the Minneapolis-Spokane-Seattle civil airway. The station was moved from its original location at Seifert Field, near Belgrade, Montana, to Pogreba Field in 1953, where it now serves as a terminal at Three Forks Airport. The Airway Radio Station was listed on the National Register of Historic Places on November 5, 1998.
