Greater Orlando Aviation Authority officials have unanimously approved a $1.8bn spending plan to build a new South Terminal Complex (STC) at Orlando International Airport, Florida, US.
The STC Phase 1-Terminal C is expected to handle the growing number of passengers at the airport.
Initiated in the 1990s, the development scheme is part of a revised capital improvement plan for fiscal 2016-2023.
Expected to begin in early 2017, the plan's first phase will construct landside and airside buildings, an airfield, ground transportation, a six-storey parking garage and utility works.
The STC and associated apron or taxiway will cover a total area of nearly 300 acres, while the airside terminal will have gates 16 to 24.
The building programme will span an area of 2.7mft², while the total expansion of Orlando Airport is expected to take 25 years.
Serving both domestic and international flights, the airside terminal gates will accommodate narrow-bodied Jumbo and Super Jumbo aircraft, reported Airport World.
GOAA executive director Phil Brown was quoted by My News 13 as saying: "Funding for the South Terminal Complex will come from several sources.
"A combination of grants, Aviation Authority funds, bonds and passenger facility charges will be used to pay for this expansive and necessary project."
The STC is slated to be fully operational by 2019.
