PORTLAND FREIGHT
Where Portland Freight Moves: the Columbia River, I-5 and I-84
The Portland-Vancouver-Hillsboro metro had about 2.54 million residents in July 2025, roughly 11,000 more than a year earlier, and most of its freight comes from one long strip on the south bank of the Columbia. The marine terminals and Rivergate sit near the spot where the Willamette joins it, with Swan Island upriver. PDX and the Columbia Corridor fill the middle, and Troutdale and Gresham hold the east end where I-84 comes out of the Gorge.
Rivergate covers 2,800 acres with more than 14 million square feet of buildings, and Terminal 6 ties Oregon to the container lines with on-dock rail. PDX handled roughly 207,000 metric tons of air cargo during 2025. Two branches leave the river strip: US 26 west to the chip plants in Hillsboro, and I-5 north over the Interstate Bridge to Vancouver, Washington.
Much of the city's rush work runs between two of those points. A spare part leaves a Columbia Corridor warehouse for a fab on Intel's Hillsboro campuses. The engineering center at Daimler's Swan Island headquarters needs a component from a supplier in Vancouver. A pump rebuilt in Gresham is due back at a crane on the docks. None of these trips is long in miles.
They are long in traffic, though. ATRI's 2026 list puts I-5 at I-84 at No. 27 among U.S. truck bottlenecks and the I-5 Columbia River crossing at No. 39, and every I-5 truck between the two states uses the Interstate Bridge. A vehicle booked for one load leaves when that load is ready, so it can get through ahead of the backups. Farther out, Seattle is about three hours up I-5, and Boise six and a half to seven hours out I-84 through the Gorge.
