Transportation officials expect the $2.8bn terminal currently being constructed at Orlando International Airport in Florida, US, to be ready by 2021.
The facility is being constructed one mile south of the original A and B terminals of the airport, reported orlandosentinel.com.
It is expected to help the airport to cope with the growing number of passengers.
Orlando International Airport currently manages almost 48 million passengers per year, which is more than the combined capacity of terminals A and B.
The new terminal, which will host airlines including JetBlue, will enable the airport to manage an additional 11 million passengers annually.
It will add 19 gates, which will accommodate up to 27 aircraft, including narrow body, jumbo and super-jumbo airplanes.
The terminal will feature automated screening lanes and an energy-efficient baggage claim system for international passengers.
It will also use facial recognition technology for arriving and departing international passengers.
The terminal project is expected to create 2,500 construction jobs, as well as approximately 250 permanent jobs during the initial phase.
The expansion of the airport terminal is being funded with bonds. It will be repaid with revenue from airline and passenger fees, parking charges, rental cars and restaurant leases.
