The Port of Seattle added the final structural beam to the International Arrivals Facility at Seattle-Tacoma International Airport during a “topping off” ceremony last week. The project, which includes a 450,000-square-foot grand hall that will be five times larger than the current 1970s-era facility, is set to be complete in the fall of 2020.

The airport continues to see growth in international air travel, with three new international airlines beginning service this year and three more scheduled to begin in 2019. The number of passengers requiring U.S. Customs clearances at the airport has doubled in the past 10 years. During peak travel periods, the number of passengers is much higher than the current facility was designed to hold, according to a statement from the Port of Seattle.

Once finished, the new International Arrivals Facility will have an 85-foot high aerial walkway and a new security corridor that will allow for the use of both gates on Concourse A for international and domestic arriving flights.

The new facility is expected to create approximately 10,600 new jobs, including 500 jobs per day during construction. The project is expected to be finished by May 31, 2020. The facility will open to the public by the fall of that year.
