Major Construction Starts on SEA's S Concourse Rebuild
ESTIMATED50% CONFIDENCEThe Port of Seattle says the work has "major construction scheduled to start in 2027", a year rather than a day, so it sits at the end of that year.[1]
The Port of Seattle's S Concourse Evolution project adds 150,000 square feet to the 1973 satellite concourse that handles most of SEA's international flights, including a new upper concourse level and dual-level boarding at selected gates, reusing customs space freed when the International Arrivals Facility opened in 2022. All phases are estimated to finish by 2034.
