SR 202 - E Lake Sammamish Parkway to 244th Ave NE - Corridor Planning Study

Planning study news

The SR 202 East Lake Sammamish Parkway to 244th Avenue NE Corridor Study was completed in summer 2019 and delivered to the Washington State Legislature Joint Transportation Committee. This study addressed near-, mid-, and long-term safety, mobility and access needs on SR 202 from East Lake Sammamish Parkway in Redmond to the SE 244th Avenue intersection southeast of Sammamish. The study provided a recommended package of near-, mid-, and long-term strategies for SR 202 in this area, consistent with WSDOT's Practical Solutions approach.

Summer 2018 - Summer 2019


State Route 202 is an important east-west link for King County communities like Woodinville, Redmond, Sammamish, Fall City and North Bend. Thanks to growth and development, traffic on SR 202 has increased in the last decade, contributing to longer travel times for commuters and freight.

To address these concerns, WSDOT studied the SR 202 corridor from East Lake Sammamish Parkway in Redmond and 244th Avenue Northeast in Sammamish. The study helped:

  • Determine priorities for future highway work or transit service adjustments.
  • Develop practical, cost-effective concepts and practices to help improve trip reliability and safety along the corridor.

WSDOT study partners included: Redmond and Sammamish; tribes; King County Metro Transit; King County Roads and Parks; Sound Transit and the Puget Sound Regional Council (PSRC). Concepts identified in the study were submitted to the Legislature on June 30, 2019.
