Route 550

Bellevue, Mercer Island and Seattle riders, we know you depend on the 550 to get you from home to work, school and activities across the region.

Questionmark icon Bus restructure impacts

The 550 will no longer stop at Rainier Avenue South due to the closure of the Rainier Freeway Station. Buses will continue to access the Downtown Seattle Transit Tunnel via I-90 and service all normal Downtown Seattle stops (International District, Pioneer Square, University Street, Westlake). This route also will not use the transit-only roadway on I-90 to get downtown. It will proceed on the I-90 mainline into Downtown Seattle.

Because travel times will increase modestly, expect to wait an extra minute or two for your bus in the afternoon rush hour, in both directions, as buses will come slightly less frequently. For each route, exact stop times and schedule will be available in August 2018 for the September 22, 2018 service change.
