The Tazewell County Airport has a new beacon to help guide airplanes along with a new automated weather system.
Other improvements include a second taxiway and apron around a hangar that opened in 2012.
Airport manager Jerry McReynolds says the beacon and the weather system will be beneficial for airplanes landing at the airport.
Other improvements include renovations to the terminal and landing strips.
The improvements cost a total $750,000.
