The Mercer Island Park-and-Ride is the community's primary public transit center with access to downtown Seattle and Bellevue in under 15 minutes. There are 447 parking spaces available and free parking is allowed for up to 24 hours. Bike lockers and racks are located nearby as well as one of the few remaining pay phones on Mercer Island.
A neighboring light-rail station placed between the I-90 roadways is planned but no final date for completion has been set.
