About This Route:

I-5 runs almost the entire length of this route, making it one of the most direct and heavily traveled corridors on the West Coast — the same highway connects Seattle, Portland, Sacramento, and Los Angeles in a nearly unbroken line. Unlike routes that cross multiple time zones, Washington and California share the same Pacific Time Zone, so there’s no clock adjustment to plan around. This route is a common one for relocation searches, given the ongoing migration between the Pacific Northwest and California’s Central Valley.
