Delridge RapidRide

Downtown Seattle to Delridge to Burien

What's happening now?

Thank you to everyone who visited the online open house and provided feedback on improvements planned for Delridge Way SW. We are reviewing all the ideas and feedback we received, and will use what we heard to help us select a preferred option as we begin designing improvements.

King County Metro is currently running a survey to help prioritize needs and opportunities around Route 120. It builds on input you shared with us this spring and will help us evaluate the performance of future improvements.

The Metro RapidRide H Line project will provide fast, frequent, and reliable public transportation between Downtown Seattle and Burien through the Delridge neighborhood. We'll be improving walking and biking to bus stops and make sure people and goods keep moving.

Project Overview

Delridge Way SW is one of seven new corridors where the we are partnering with King County Metro to enhance transit connections and upgrade existing bus routes to Metro RapidRide service. Upgrading Metro Route 120 into the RapidRide H Line will keep people moving by:

  • Keeping buses frequent and on-time
  • Adding more buses at night and on weekends
  • Upgrading to Metro RapidRide bus stops with lighting, real-time arrival info, and more
  • Improving sidewalks and paths for people walking and people riding bikes

We're working to balance the needs of everyone who uses the corridor, whether they're in a bus, a car, walking or riding a bike.

Questions about RapidRide or how it could benefit you? Get all the details at Seattle's RapidRide Expansion Program website or visit Metro's RapidRide website.

How can I get involved?

We're always interested in meeting with community and neighborhood groups that want to learn more about the project and make their voices heard. You can request a briefing by emailing or calling (206) 684-5189. More details and opportunities to get involved will be announced as they are scheduled.

Do you live outside the city of Seattle?

King County Metro is bringing RapidRide amenities and improving service between the Seattle City limits and Burien. Additional project funding for these improvements comes from grant sources that Metro has already secured. Metro will be conducting public outreach about the project changes in these areas in 2018.
