This project will convert the recently completed 156th St. NE overcrossing at Interstate 5 to a full Single Point Interchange, thereby improving access to North Marysville, Lakewood and Smokey Point employment centers. The project is fully funded under the Connecting Washington Program, approved by the Washington State legislature during the summer of 2016. Preliminary work on the project is estimated to begin in 2025. Construction would be complete by end of 2031.
SR531 will be fully widened from I-5 to 67th Ave. NE, providing much needed capacity with links to the Cascade Industrial Center. The project is funded under the Connecting Washington Program, approved by the Washington State Legislature in the summer of 2015. To view project details, visit the WSDOT project page.
