Project Overview: The North-South Corridors Study is conducting a travel study of north-south congested corridors and identifying potential operational solutions and capital improvements.

  • Determine short-term improvements that can be implemented within the next six years for Willows Road and 172nd Avenue NE to improve access and safety along those two corridors
  • Determine the ultimate long-range improvements needed for each of the corridors within the study
  • Develop criteria and prioritize the long-range improvements needed in the study area
  • Conduct community outreach and engagement efforts throughout the study
