Established as a unique marine cargo operating partnership between the ports of Tacoma and Seattle, The Northwest Seaport Alliance serves as a paramount example of successful collaboration in the maritime industry. The alliance maintains a strong relationship with Alaska and provides quicker U.S.-to-Asia transits thanks to Washington State’s strategic location in the Pacific Northwest.

A Pioneering Endeavour

The Northwest Seaport Alliance, the first of its kind in North America, was conceptualized and brought to life with a remarkably bold vision. Instead of competing, the ports of Seattle and Tacoma decided to join forces to establish an alliance, aiming to compete on a global scale with enhanced efficiency. The alliance was officially formed in August 2015, marking an unprecedented, historical first in North America.
Genesis and Evolution
In order to increase maritime freight and employment opportunities in the Puget Sound area, a partnership was formed to fortify the Puget Sound gateway. Federal Maritime Commission permission and extensive public outreach led to the alliance’s creation.
Governing Structure
The Seattle and Tacoma ports, as equal members of the Northwest Seaport Alliance, are managed by their respective elected commissioners. Five commissioners, chosen at large by the county voters, oversee each port. Port and Alliance policy is set by these individuals during their four-year periods in office.
A Significant Economic Contributor
Maritime cargo operations in the Tacoma and Seattle harbors supported more than 58,400 jobs in 2017, generating nearly $5.9 billion in economic activity. That same year, maritime cargo activity generated $135.9 million in state taxes, which support education, roads, and police and fire protection in local communities.
A Hub for Diverse Cargo Operations
Shipping containers, bulk, breakbulk, project/heavy-lift goods, vehicles, and trucks converge at the Northwest Seaport Alliance. The alliance’s robust infrastructure for smooth cargo operations is demonstrated by its direct rail connections to the Midwest and Pacific Northwest areas of the US, established by Union Pacific Railroad and BNSF Railway.
Container Handling

The alliance is the fourth-largest container gateway, which is a testament to its efficiency and capability in handling large volumes of containerized cargo. Both harbors are equipped with a total of ten container terminals, twenty-three berths, and forty-seven cranes, making them suitable for both the current and future mega-ships.
Non-Container Cargo Operations
In addition to container handling, the alliance also manages seven non-container terminals used primarily for breakbulk cargo and automobiles via roll-on/roll-off ships. This versatility in cargo operations allies an ideal choice for diverse shipping requirements.
A Commitment to Sustainable Growth
The Northwest Seaport Alliance prioritizes responsible, sustainable growth. It has initiated several projects focused on reducing diesel emissions, developing new ecologically friendly technology, increasing renewable energy, and undertaking habitat restoration jobs.
An Award-Winning Business Environment
The Northwest Seaport Alliance is recognized for its ease of doing business. With naturally deep-water harbors and the ability to handle a wide range of cargo, the alliance is optimally positioned to meet the burgeoning needs of trans-Pacific trade. The coalition also offers various tools and resources, including documents, reports, and publications, to help businesses navigate the process.
A Response to Global Challenges
The onset of COVID-19 posed a global challenge to the smooth operation of the maritime industry. Despite this, the Northwest Seaport Alliance gateway remained open and operational during the worldwide pandemic. To guarantee the gateway’s optimal operation, the alliance collaborated closely with operators of maritime terminals, labor, warehouse firms, and supply chain partners.
Recognizing Outstanding Contributions

The Northwest Seaport Alliance believes in recognizing customers for their outstanding achievements and contributions. Green Marine is the most extensive voluntary environmental certification program in North America for the marine industry, and it participates in that program.
One organization that has shown the value of working together is the Northwest Seaport Alliance. By combining their resources and expertise, the ports of Seattle and Tacoma have created an entity that is more than the sum of its parts, contributing significantly to the economy of Washington and the United States. Its commitment to sustainable growth and customer recognition further cements its position as a leader in the maritime industry.
