The Port of Tacoma is a publicly owned and managed port district established by Pierce County voters in 1918. Today it is a leading container port, serving as a "Pacific Gateway" for trade between Asia and the central and eastern United States as well as the Northwest. Most of the maritime commerce between Alaska and the lower 48 states also passes through Tacoma. A suite of factors that the Port calls the "Tacoma Advantage" have contributed to its success. The advantages begin with the port's location on the Tacoma tideflats along the deep waters of Commencement Bay. The Port's acreage has allowed it to create efficient intermodal transportation connections between ship and road or rail, often right on the dock. Cooperation between Port management and union longshore workers has provided an additional advantage, helping bring many of the world's largest container lines to Tacoma.
