Port of Seattle’s Terminal 46 (T46) is a critical node in a trade corridor extending from Asia to the U.S. Midwest and beyond. T46 was one of the first container terminals in the U.S., helping enable the massive growth of U.S.-Asia trade of the second half of the 20th Century. The facility is located in the state’s largest manufacturing and industrial center and experienced an 126% growth in exports from 2003-2013. Today it remains one of our nation’s premier trade infrastructure assets.
After several decades of service, investments must be made at T46 to address maintenance issues that threaten the reliability, cost-effectiveness and efficiency of the trade corridor and to compete with major upgrades at Canadian ports. The T46 Modernization Project will perform maintenance to extend the service life of T46 by 25 to 30 years. The project will make enhancements to enable the terminal to service two super post-Panamax ships simultaneously. The Project will improve port competitiveness and protect decades’ worth of investment. The TIGER Project’s components, described in greater detail below, are:
  • T46 Dock Rehabilitation: Repair container berth pile caps and deck panels that have deteriorated with the passage of time.
  • T46 Stormwater Quality Improvements: Treat runoff from the terminal to achieve the highest water quality standard in the nation.
  • T46 Paving: Repair terminal apron and container yard that is currently deteriorating and causing safety concerns.
  • T46 Crane Rail Extension: Extend dock crane rail to allow an additional 100-foot gauge crane to work the full length of the terminal.
  • Argo Safety and Congestion Improvement Connector Road: Improve safety and reduce traffic congestion by providing a shorter, more direct link from seaport terminals to Union Pacific Railroad’s Argo intermodal yard. Project will grade-separate drayage truck traffic from State Route (SR) 99, allowing trucks to avoid cutting across three lanes of traffic in a few hundred feet for the left turn into the rail yard.
  • T117 Public Shoreline Access Development: Convert T117 parcel into public shoreline access and restored fish and wildlife habitat. Designated as a complimentary offset to developments at T46, this element will create a multi-use community space adjacent to an underserved neighborhood.

Rail and Highway Connections

The Port of Seattle is served by two Class I railroads and is located at the intersection of Interstate 5 and Interstate 90. Over 60% of imports and a substantial portion of Seattle’s exports consist of cargo to and from the US heartland.
