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.
