King County Metro, in partnership with the Seattle Department of Transportation (SDOT) and the City of Burien, is working to upgrade Metro Bus Route 120 — one of our 10 busiest routes — to the RapidRide H Line.
We will be sending email updates monthly to keep you informed on what to expect with construction activities over the coming weeks. We’ll also be reaching out to route neighbors, businesses, and local community organizations throughout construction to notify them when and where work will happen, as well as what impacts to expect.
Please feel free to share this information with your neighbors and encourage them to sign up for project email updates.
