Project overview
The Marine Drive and 88th Street Northeast interchanges near Marysville are frequently congested, with traffic backing up onto I-5. They're also two of only three access points to the Tulalip Tribes reservation. The Tribes are leading this project to improve access and mobility at the interchanges
What to expect
In August 2021, the Tulalip Tribes and a study support group selected a series of roundabouts at 4th and 88th streets as the preferred solution. This solution is now undergoing environmental review and preliminary design. More information about how construction will affect highway users will be provided closer to the start of construction.

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.
