Mountains to Sound Greenway - I-90

Department of Transportation.

Drive east from Seattle on I-90 through pastoral valleys, lush forests and a dramatic mountain landscape. Visit historic towns and scenic spots for forest walks or challenging hikes. Cross the Cascades into a drier climate where coal mining built pioneer towns on the way to the Columbia River.
