During the first half of this year, Portland handled 162,504 vehicles, a 19.9 percent increase from a year earlier. The growth came atop an 11 percent rise in 2016 to 291,242 units that made Portland the seventh-busiest US auto port.

The increased vehicle traffic attracted relatively little notice amid the International Longshore and Warehouse Union’s (ILWU) well-publicized battles with ICTSI Oregon, which this year gave up its lease at the Terminal 6 container terminal after carriers exited the port.
