Completion: Phoenix Sky Harbor[1][2] release, 21 Sep 2026: "Construction could potentially begin in late 2029 with an opening in late 2033" (late 2033 read as by the end of 2033).
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.
