King County Metro, in partnership with Seattle Department of Transportation and City of Burien, is upgrading Metro Bus Route 120 to RapidRide H Line.
When the RapidRide H Line launches, it will provide more frequent and reliable connections from neighborhoods in Burien, White Center, and West Seattle to downtown Seattle and South Lake Union. It will also continue the needed connections to other transit services such as the Link light rail.
The H Line project also includes important pedestrian and vehicle safety improvements, including enhanced bus stops, a dedicated bus lane, and more.
Project Location
Ambaum Boulevard SW between SW 116th Street (north city limits) and SW 150th St (Burien Transit Center).
