- We are now accepting bids from pre-qualified contractors for the second construction contract of the I-90 Hyak to Keechelus Dam Project.
- We have completed construction activities on the first I-90 contract!
- Crews built a detour bridge near the Gold Creek area that will be used next year to detour traffic around the construction area.
- Crews also excavated approximately 265,000 cubic yards of material from Keechelus Lake to mitigate for the project’s future impacts on reservoir water storage.
The I-90 Snoqualmie Pass East - Hyak to Keechelus Dam project extends 5 miles from milepost 55.1 to 59.9.
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 we address long term solutions for I-90 from Hyak to Easton?
WSDOT worked 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 consensus for a long-term vision for the I-90 corridor between Hyak and Easton. This effort culminated in a draft environmental impact statement (DEIS) that outlines improvements to meet projected traffic demands, improve public safety, and meet identified project needs along this 15 mile stretch of I-90. The Final EIS is now published.
The End Result: Safety and Mobility
Travelers will experience a safer, more efficient six-lane freeway, minimized closures due to avalanches and rock slides, and a smoother ride due to new pavement designed to last 40 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 animals and the traveling public. WSDOT will begin to improve the I-90 Snoqualmie Pass East corridor with the funded first five miles - I-90 Snoqualmie Pass East Hyak to Keechelus Dam Project.
Current funded I-90 Snoqualmie Pass East projects include:
