King County Metro is conducting a long range study to identify potential sites for a future park & ride facility within the vicinity of the I-90 and State Route 18 interchange in accordance with HB 2190, adopted by the State Legislature and signed into law in 2012.

The study will identify up to three potential sites for a future park & ride facility within the study area. The study will also provide a preliminary layout, and a design and construction cost estimate, for each potential site.

Study area

King County Metro I-90/SR 18 Park & Ride Study Area:


The park & ride study is scheduled for completion by June 30, 2015. A final report will be produced summarizing the evaluation and identifying the top three potential sites that best meet the evaluation criteria identified for a future park & ride facility, if it is determined that one is needed in this area.

Project funding

The Washington State Department of Transportation (WSDOT) directed Federal Highway Administration (FHWA) grant funding to King County Metro for this park & ride study. The project funding is for this long range study only. King County Metro does not have funding for design or construction of a new park & ride facility at this time.

Local coordination

A technical advisory committee (TAC) has been established for this project with representatives from WSDOT, the City of Snoqualmie, the Puget Sound Regional Council, and King County. The TAC is providing input on the evaluation criteria and will review the results of technical analysis completed to support the selection of the finalist sites.

Please note

Although this is a long-range study, your comments are welcome on design characteristics you would like to see incorporated in a future park & ride facility (e.g. special lighting, weather protection, bicycle accommodations, sustainability features, and other ideas).
