Port Sets Budget for Overhaul of SEA Airport Concourse
The Port of Seattle Commission approved a final budget of $399 million for the next major upgrade to Seattle-Tacoma International Airport’s main terminal.
The four-story addition will add more than 145,000 square feet and open up the area where the low-ceilinged C and D concourses meet.
Early work on the project broke ground a year ago, with major construction expected to begin in early 2024 and wrap up in 2026.
