Beginning in January 2020, The Tulalip Tribes hosted monthly Study Support Team (SST) meetings. The SST meetings included participation from the project stakeholders including FHWA, Snohomish County, the City of Marysville, WSDOT, and Community Transit.

The purpose of the SST meetings was to collaborate with stakeholders, develop the project purpose and need, review existing conditions, prepare the baseline and contextual needs, develop and refine improvement alternatives screening, and support the selection of a preferred alternative that meets the needs.

Alternatives and Analysis Selection

The SST team reviewed several alternatives to identify a preferred alternative at each interchange. Click the links below to view information about the preferred alternatives selected.

In the Fall of 2021, an Online Open House was presented to allow the community to provide comments on the project status and preferred alternatives selected.

Responses to questions received are summarized in the Frequently Asked Questions (FAQs).

Based on the comments received and the selection of preferred alternatives, the Tulalip Tribes will proceed with studying how the project may affect people and the environment. The results of the study will be published in an Environmental Assessment that will be shared with the public for additional feedback and comments.
