Find out why I-90 is an important transportation corridor in Washington state.

I-90 Corridor Overview  

Interstate 90 is a critical transportation corridor, linking Puget Sound to eastern Washington and beyond. The I-90 traveler may experience congestion, delays due to avalanche closures, rough pavement conditions, rock slide activity and potential wildlife collisions on the highway. The uninterrupted movement of people, freight and business over Snoqualmie Pass is essential to our quality of life and the economic vitality of Washington State. WSDOT is expanding I-90 to meet both the current and future needs of those who travel the Pass.

How will WSDOT address long term solutions for the I-90 Corridor from Hyak to Easton?

WSDOT is working with the United States Forest Service (USFS), the United States Bureau of Reclamation (USBR), Federal Highway Administration (FHWA), United States Fish and Wildlife Service (USFWS), Washington Department of Fish and Wildlife (WDFW), Department of Ecology, Environmental Protection Agency, cities, counties, and community groups to develop a long-term vision for the I-90 corridor between Hyak and Easton. This effort culminated in a draft Environmental Impact Statement (EIS) that outlines improvements needed to meet projected traffic demands, improve public safety, and meet identified project needs along this 15 mile stretch of I-90. The Final EIS was published in 2008.

The End Result: Safety and Mobility

Travelers will experience a safer, more efficient six-lane freeway, minimized closures as a result of avalanches and rock slides, and a smoother ride due to new pavement designed to last 50 years when all improvements are completed. Wildlife habitat on either side of I-90 will be reconnected with the installation of new bridges and culverts, protecting both wildlife and the traveling public.
