Some good news from the new Northwest Seaport Alliance (the combined ports of Seattle and Tacoma): Yesterday the largest container ship that has ever come to the Puget Sound arrived in Seattle. With an 11,400 TEU capacity, the CMA CGM Callisto holds 40 percent more cargo than the Puget Sound’s regular clientele.

“Ships continue to get larger, and we are ready for them,” said John Wolfe, Northwest Seaport Alliance chief executive officer. “We are investing in our terminals and road and rail infrastructure to handle more cargo and the super-post-Panamax ships moving into the trans-Pacific trade.”

We’ve written a lot about the importance of maintaining the competitiveness of our ports (see here, for example). To that end, it’s a good thing that our ports can accommodate these larger ships.
