4TH STREET AND 88TH STREET NE CORRIDOR IMPROVEMENTS PROJECT
4TH STREET AND 88TH STREET NE CORRIDOR IMPROVEMENTS PROJECT
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.
The SST team reviewed several alternatives to identify a preferred alternative at each interchange.
The preferred alternatives included a series of roundabouts along both 4th and 88th Streets. Click the graphics, located to the right, for information about the preferred alternatives selected for the project.
Two Online Open Houses were held in the Fall of 2021 and July of 2023 to allow community comments on the project status, preferred alternatives, updates on the design, environmental documentation, and project schedule. Responses to questions received are summarized in the Frequently Asked Questions (FAQs).
