The population of Snohomish County increased by over 400,000 residents between 1980 and 2018. It's expected to gain another 200,000 residents by 2035. This explosive growth increased the number of vehicles using I-5 between Everett and Marysville, with around 65,000 vehicles traveling in the northbound direction alone each day. Drivers frequently experience heavy congestion and long commute times. In addition, traffic at the I-5/SR 528 interchange in Marysville often backs up, creating additional delays.
The 2015 Connecting Washington transportation package provided funding for:
WSDOT formed a Stakeholder Advisory Group (SAG) made up of representatives from area cities, agencies, and tribes to make recommendations on how to reduce congestion. In August 2019, with feedback from the SAG, WSDOT selected a preferred alternative. WSDOT will build a permanent fourth lane for HOVs, extending the existing HOV lane in Everett to SR 529. The three general-purpose lanes will remain in place. WSDOT chose this alternative after studying data that shows a high percentage of HOV-eligible vehicles regularly travel through the area. In addition, WSDOT is looking into how the improved interchange can serve people who bike and walk on SR 529 between Marysville and Everett.
The benefits of a new HOV lane and an improved interchange include:
