From the News Tribune:

Last year’s container traffic through the ports of Tacoma and Seattle was the highest since 2007, according to a news release from the Northwest Seaport Alliance.

The seaport alliance formed a little more than a year ago as a partnership between the Port of Tacoma and the Port of Seattle. The alliance manages cargo business for both ports. The data compare traffic through both ports, both before and after they formed the alliance.

In 2016, the alliance managed more than 3.6 million TEUs, or 20-foot-equivalent container units, an increase of more than 2 percent from 2015 container volumes.
