Interstate 90 |
The second most important highway in Washington heads east from the most important (Interstate 5) at Seattle and crosses Lake Washington to Bellevue. It crosses the Cascades through Snoqualmie Pass and descends through Ellensburg on its way to the Columbia River. After crossing the Columbia at Vantage, it continues east, through Moses Lake and Ritzville before reaching Spokane, just before the Idaho border.
