SR 526 - Corridor Improvements

Needs & benefits

Everett’s continued economic and population growth is contributing to worsening conditions on “the Boeing Freeway,” used by an estimated 74,000 travelers each day commuting to and from work, making deliveries, visiting tourist attractions and catching flights at the new Paine Field commercial airport terminal. 

In 2017, the Washington State Legislature directed WSDOT to identify improvements to address a variety of issues affecting SR 526 users. To help, WSDOT convened a project advisory group made up of representatives from the cities of Everett and Mukilteo, Snohomish County, Boeing, Community Transit, Sound Transit, Washington Trucking Association, and the Economic Alliance Snohomish County.

The advisory group determined the project should focus on the following needs: 

  • Improve peak period travel times for all vehicles
  • Improve freight access to and from SR 526 and the SW Everett industrial area and Paine Field/Boeing industrial area
  • Accommodate for future corridor transit needs, including the light rail expansion
  • Address safety for all vehicles and highway users along the corridor


  • 2017: Funding allocated from the Connecting Washington transportation package
  • 2018-2020: Community engagement and concept development
  • 2020-2021: Engineering and environmental documentation
  • 2021-2022: Implement improvements
