I-5 - SR 528 - Marine Drive and 88th St. NE Interchanges - Tulalip Tribes lead

There are only three access points to the Tulalip Tribes reservation from Interstate 5: Marine Drive/4th Street Northeast, 88th Street Northeast, and 116th Street Northeast. After completing improvements at 116th Street Northeast several years ago, the Tribes are planning major improvements to the remaining two. 

A preferred solution was selected in August 2021. The preferred solution includes a series of roundabouts along both 4th and 88th streets. Environmental review and preliminary design for the roundabouts is now underway. 

Improving these interchanges will support economic vitality and livability for the Tribes. Safe and efficient access to and from the reservation supports the transportation of goods, economic development, higher education, jobs and healthcare for members of the Tribe.

These two interchanges routinely experience heavy congestion and mobility challenges for cars, trucks, pedestrians, and transit users. Frequently, drivers exiting to enter the Tulalip Tribes reservation or the city of Marysville experience off-ramp backups that extend onto I-5.

The Tribes are working with a study support group consisting of representatives from WSDOT, the Federal Highway Administration, Snohomish County, the city of Marysville, and Community Transit to review the existing issues, and develop and refine the preferred solution.
