Welcome to the Terminal 5 Improvements Project online site.

The Port of Seattle, through The Northwest Seaport Alliance (NWSA), a marine cargo partnership between the Port of Seattle and the Port of Tacoma, has approved a project to upgrade Terminal 5 to handle ultra-large container ships with a capacity of up to 18,000 containers.

The Terminal 5 Project will enhance and maintain the competitiveness of the region’s trade gateway and provide economic benefits including jobs, market access for exports grown and made in the region, and imports beneficial to the regional and national economy. Construction began in July 2019.

How to use the online site:
