Where Washington trucks run
I-5 (north-south) and I-90 (east-west over Snoqualmie Pass) are the main truck corridors, serving the Ports of Seattle and Tacoma, the Kent Valley warehouse district, Spokane and the Columbia Basin agricultural region. The busiest freight markets include Seattle, Tacoma, Spokane, Vancouver, Tri-Cities (Kennewick, Pasco, Richland) and Yakima.
The Northwest Seaport Alliance ports of Seattle and Tacoma generate heavy container drayage, the Blaine crossings handle Canada trade, and winter traction and chain rules on Snoqualmie, Stevens and White passes regularly affect trucks.
