The expansion will create a third terminal to handle projected traffic growth.
During a San Antonio City Council meeting, the director of airports, Jesus Saenz, unveiled the Terminal Development Programme (TDP), which includes the design and construction of the new terminal.
TDP is part of the Strategic Development Programme that secured the City Council’s clearance last November.
The new terminal C will add 17 gates to SAT.
There are currently two projects underway to create five new gates at the airport, however, even with these projects, it is reaching capacity.
Saenz said: “This is an investment in our city’s future and our economic growth. Our ultimate goal is to elevate the passenger experience.
“We initiated the implementation of the Strategic Development Programme, which encompasses the TDP, the day City Council approved the plan.”
The terminal project will see the creation of a ground transportation centre, parking garage and terminal road realignment to meet passenger requirements over the next two decades.
These new facilities are expected to be completed by 2028.
Saenz added: “We are going to be the airport of the future. We are on track to give travellers everything they need – and then some. This is going to be the airport the entire San Antonio community will be proud of.”
The Airport System has also initiated the next phase of the airfield expansion, which will extend the existing runway by up to 10,000ft.
