Welcome

The Seattle Department of Transportation and King County Metro are partnering together to bring RapidRide to Delridge Way SW.

In collaboration with King County Metro, we’re working to make Delridge Way SW a better bus street. Since 2015 we have been working with community members to incorporate feedback on street design and upgrades to Route 120 into the RapidRide H Line. RapidRide H Line will connect the Delridge neighborhood with faster, more frequent transit service to Downtown Seattle, South Lake Union and Burien while providing connections to other buses and Link light rail. We appreciate your involvement.

What's happening now?

Construction has started for the Delridge Way SW - RapidRide H Line project. Construction started in June 2020 and will last through 2022. During this time our outreach team will continue to meet with local organizations and businesses about upcoming work and notify the community with email updates for what work to expect. Construction timelines are always subject to change and we will continue to provide updates if and when they are impacted. 

To learn about the latest construction updates, sign up for our email updates and view our email update archive.

The closure of the West Seattle High-Rise Bridge has significantly impacted the way people move through West Seattle in recent months. As we continue to make on the ground improvements to keep people moving now, we will also continue to invest in long-term projects that help us build an even stronger, connected, and more livable West Seattle. It is critical that we implement both short- and long-term improvements while we simultaneously pursue all options available to reopen the high-rise bridge, which is why we are moving forward with this much-needed project along Delridge Way SW to add a new rapid transit line, improve safety, enhance bike infrastructure, and repair roads in poor condition.

We know this is a challenging time for all in and around West Seattle with the high-rise bridge closed and with the critical use restrictions placed on the Spokane Street Low Bridge.There is no perfect time to start a project, but now is the time to leverage this closure to build greater capacity and mobility so that when the bridge does reopen and as the RapidRide comes online, West Seattle can move forward, full steam ahead, stronger than ever before.

Construction is anticipated to begin in June and wrap up in 2022. As we get closer to construction, we will provide advance notice through a variety of ways including text messages, website updates, and email updates. Please sign up for our email updates to stay up to date on project progress and upcoming impacts.

Improve transit travel time and reliability throughout the corridor
RapidRide H Line will provide up to 10-15% time savings compared to Route 120

icon

Reduce overcrowding of existing bus capacity
Buses will come more frequently and will serve 7,100 new daily boardings by 2035

icon

Improve pedestrian and bicycle safety and connections to transit
Upgraded pedestrian facilities and new bike facilities are included throughout the project corridor

icon

Reduce GHG emissions
RapidRide H Line will help promote use of alternative modes of transportation to driving alone

Final design

Community priorities we heard and incorporated into the design:

"Fix potholes and bad pavement"

  • We’re planning to pave between the West Seattle Bridge and SW Orchard St and make minor repairs in the rest of the corridor

"Make buses faster and more frequent"

  • We’re extending the northbound bus only lanes to reduce traffic
  • Added transit priority signals to keep buses moving

"Reduce speeding and create a neighborhood feel"

  • We're adding new crosswalks and flashing beacons to improve pedestrian safety
  • Pedestrian walk signals will be timed to give people walking a head start at intersections
  • Flowering planters will be added to create a neighborhood feel

"We value the bus as a neighborhood connector"

  • We’ve worked with Metro to have RapidRide stations about 1/3 mile apart instead of 1/2 mile apart

"We want safer and more accessible options for people biking"

  • We are improving wayfind signage, adding speed bumps, and repainting channelization along 26th Ave SW.
  • Traffic diverters have been included at SW Genesee St and SW Brandon St along the 26th Ave SW neighborhood greenway.
  • We are also creating a new neighborhood greenway along 18th Ave SW by SW Myrtle St to avoid the staircase on 17th Ave SW.

Preparing for construction

We are getting ready for construction! We anticipate construction beginning in June 2020. We have selected a contractor to help us pave the street and build the walking, biking and transit improvements described in our design. We anticipate breaking ground this summer with construction to continue into 2022.

We also want you - especially those who live, work, or travel on Delridge Way SW - to start preparing today for major construction. Construction will be disruptive and look similar to the work on the nearby 35th Ave SW/ SW Avalon Way Project.
