Reconstruct terminal

The Port of Seattle received a $146.03 million Project Grant from the Federal Aviation Administration (FAA) under the Airport Improvement Program, Infrastructure Investment and Jobs Act Programs, and COVID-19 Airports Programs (CFDA 20.106), awarded on August 12, 2025, with an ultimate completion date of August 11, 2029. This grant funds structural, seismic, and building system upgrades to reconstruct approximately 86,000 square feet of the existing Terminal Building Concourse S at Seattle-Tacoma International Airport in Burien, Washington. The funding supports Phase 3 construction activities for terminal infrastructure that has reached the end of its useful life, and is coordinated with an associated Airport Terminal Program grant that funds the remaining eligible project costs.

The project represents a critical modernization initiative for Seattle-area airport infrastructure, addressing aging terminal facilities through comprehensive structural and seismic improvements. As a local government entity operating Seattle-Tacoma International Airport, the Port of Seattle leverages this federal investment to enhance aviation infrastructure capacity and safety for the traveling public and regional economy. The grant is part of the FAA's broader strategic mission to develop and maintain a nationwide system of adequate public-use airports supporting civil aeronautics and long-term economic benefits.
