The North Sammamish Park-and-Ride will provide up to 200 parking spaces in the north end of the City of Sammamish. Regional transit connections will include bus service to the future Link 2 Line, serving Redmond, Bellevue, Mercer Island and Seattle.

We’ll build this lot within the Sound Transit district, along the 228th Avenue NE/Sahalee Way Northeast transit corridor, north of Southeast 8th Street. Sound Transit will determine the exact location of this facility in partnership with the City of Sammamish and King County Metro.

Project timeline

On Aug. 5, 2021, the Sound Transit Board adopted a realigned capital plan to address steeply rising construction and real estate costs affecting many voter-approved regional transit expansion projects.

The Board’s adopted plan identifies 2045 as the date we’ll open the North Sammamish Park-and-Ride, based on current revenue projections and cost and utilization estimates. This change coincides with the opening of the South Kirkland to Issaquah Link light rail extension.

We’ll track fiscal challenges very closely as we work with partner jurisdictions and stakeholders to advance this project.

Project Benefits

  • Regional connections to existing bus service and future service to the Downtown Redmond Link Extension, to serve Redmond, Bellevue, Mercer Island and Seattle.
