The Sound Transit Park-and-Ride Project on Mercer Island opened in early 2008 and includes a two-story parking garage at the previous Mercer Island park-and-ride lot site. The garage is owned and operated by Sound Transit and provides 447 parking stalls on two levels, increasing the capacity of the previous lot by approximately 200 stalls. Improvement to the bus boarding areas along North Mercer Way doubled their capacities, and provided new bus shelters, bicycle lockers, lighting, and signage. Additional project amenities include CCTV surveillance, landscaping, public art, and bike routing.

Before the COVID-19 pandemic, the Park-and-Ride was full by about 7:00am on most weekdays; usage is still rebounding with ongoing changes in daily commute patterns. To learn about reaching the Park-and-Ride by foot, bicycle, or bus, view the City's Getting Around page.
