The Denver Post reports the Dallas-based airline announced plans Wednesday for the 130,000-square-foot (12,100-square-meter) hangar that can fit three Boeing 737 aircraft.
Southwest aims to complete construction before the end of 2020.
The hangar will be the seventh in airline's maintenance network. It currently has facilities in Atlanta, Chicago, Dallas, Houston, Phoenix and Orlando, Florida.
Southwest employs about 4,200 people in the Denver area, including 75 maintenance workers.
Southwest CEO Gary Kelly says the airline expects to have 224 daily departures from Denver by August, with more routes planned.
He says the hangar is evidence of the airline investment into the community.
