4TH STREET AND 88TH STREET NE CORRIDOR IMPROVEMENTS PROJECT

Accomplishments

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).

In July 2023, a second Online Open House was launched. This update provided new information on the design, environmental documentation, and project schedule. The FAQ page has been updated with additional information to help address public comments.
