Phoenix Sky Harbor Starts Building Its Third Terminal
Sky Harbor's West Terminal, the airport's first new terminal since Terminal 4 opened in 1990, is scheduled to go into construction in 2029 and open in 2033, with the number of concourses and gates still to be decided. The airport puts the likely cost at around $4.5 billion, paid for with passenger facility charges, bonds and airport funding rather than tax dollars.
- Phoenix Sky Harbor plans a new terminal on the airport's west side, between Terminal 3 and Taxiway U - the first new terminal construction since Terminal 4 opened in 1990[1]
- The published timeline, marked subject to change, runs planning 2025-2026, design procurement 2027, design 2028-2030, construction 2029-2033 and opening 2033[1]
- The narrative is more hedged than the table: a visioning phase started in early 2026, design procurement is "anticipated" in 2027, and construction "could begin in late 2029, with a potential late 2033 opening"[1]
- The final cost has not been determined; the project "could likely cost around $4.5 billion", with the actual budget set during the terminal planning process taking place in 2026[1]
- Funding comes from passenger facility charges, bonds and airport funding; "No tax dollars will be used"[1]
- Still undetermined: the number of concourses and gates (to be based on day-one passenger demand expected in 2033, with a modular design), airline assignments, the passenger split between Terminals 3, 4 and the new terminal, and the terminal's name or number[1]
- The airport gives the reason as Terminals 3 and 4 being fully built out and unable to accommodate more gates[1]
- Some roadway construction will be required during the build; the PHX Sky Train will keep providing terminal access to reduce roadway impacts[1]
- The page links a press release, "New Terminal Coming to America's Friendliest Airport", dated May 7, 2024[1]
