Burien / White Center / Westwood Village / North Delridge / Downtown Seattle

We’re working to transform Route 120—one of our 10 busiest routes—into the new RapidRide H Line.

Public transit is an important part of how we will meet the diverse needs and priorities of our rapidly growing region. Our current growing demand for transit, plus future needs identified in our cities’ growth plans, require access to public transportation that is fast and on-time.

When the H Line is launched in 2021, it will come more often and be more reliable (on-time) than Route 120 is today. It will give riders in Burien and White Center frequent connections to several West Seattle neighborhoods, downtown Seattle along Third Avenue, other buses, and light rail.

As we plan this transition, we’ll gather input from affected communities and riders on any changes we consider.

What’s happening now?

Environmental Review

Metro is the lead agency for the project’s review under the State Environmental Policy Act (SEPA) and has completed a SEPA checklist. Metro’s SEPA Responsible Official has determined that the project will not have any significant impacts on the environment. The Determination of Nonsignificance (DNS) will be published on Nov. 4, 2019, in the Daily Journal of Commerce and The Seattle Times.

The public is invited to provide comments on the DNS and the checklist. Comments must be provided no later than 5 p.m. Nov. 18, 2019. Please see the DNS for more information on providing comments and submitting appeals.

Why convert to RapidRide?

Route 120 ridership

In September 2017, Route 120 served 80 bus stops and on average provided more than 9,200 trips each weekday, 5,600 on Saturdays, and 3,900 on Sundays. Here’s how the weekday trips broke down by time of day:

  • AM Peak = 24%
  • Midday = 33%
  • PM Peak = 29%
  • Evening/Night = 14%

RapidRide H Line improvements

  • Buses will come more often and be more reliable (on-time).
  • More service will be added at night and on weekends.
  • Some bus stops will be upgraded with lighting, real-time arrival information, off-board ORCA card readers, and more.
  • Sidewalks, street crossings, and paths for getting to stops will be improved for pedestrians and bikes, and for those with limited mobility.
  • The Seattle Department of Transportation plans to improve access to transit along Delridge Way SW, and is including bicycle and pedestrian improvements as part of the project. These may include upgraded crosswalks and intersections, new crosswalks, better connection to nearby greenways, and a possible protected bike lane on Delridge Way SW.

Project partners

We’re working with partner jurisdictions to help keep what’s great about Route 120 while also improving access to bus service. They’ll help us find new ways of helping people get where they need to go, and collaborate with us to make roadway and corridor improvements that support RapidRide service.

Community involvement

We’re doing several rounds of outreach to the public about this project.

Preliminary design

Engagement focuses on community needs and priorities for improving bus service and making it easier to get to transit. We ask about needs and priorities, conditions that should be improved, and how to prioritize project opportunities. We also ask for feedback on early design concepts. After we review the community’s input and recommendations, we use them to identify a preferred alternative.

Final design

We reach out for community feedback on the preferred alternative and concepts for change, and work with our partner agencies to refine, improve, and finalize the project design.

After the project design has been adopted, we update the community on final details and gather input on how to be a good neighbor during H Line construction.


We work to provide project updates before major activities and milestones, minimize construction impacts, and assist community members who have issues or concerns.
