The Northwest Seaport Alliance

The Northwest Seaport Alliance brings together two of the premier harbor facilities in North America to form a single, integrated gateway for marine cargo. The ports of Seattle and Tacoma joined forces in August 2015 to unify management of their marine cargo facilities, strengthening the gateway and attracting more marine cargo to the Puget Sound region. We are the third largest container load center in North America, and regional marine cargo facilities are also a major center for bulk, breakbulk, project/heavy-lift cargoes, automobiles and trucks. Strategically located in the northwest corner of the U.S., we offer shorter transits from Asia, and are the first and last ports of call for many trans-Pacific liner services. We pride ourselves on being proactive and performance-driven, and put unrelenting focus on delivering on a promise of operational excellence and best-in-class service for our customers worldwide. Make our advantages yours.
