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 connect 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, but we will continue to provide updates if and when stakeholders will be impacted.

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 began in June 2020 and is scheduled to wrap up in 2022. As we continue through construction, we will provide advance notice of work happening 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.

RapidRide H Line will provide up to 10-15% time savings compared to Route 120
Reduce overcrowding of existing bus capacity
Buses will come more frequently and will serve 7,100 new daily boardings by 2035
Improve pedestrian and bicycle safety and connections to transit
Upgraded pedestrian facilities and new bike facilities are included throughout the project corridor
Reduce GHG emissions
RapidRide H Line will help promote use of alternative modes of transportation to driving alone

Compare existing and future conditions
To view the existing or future cross-sections that are typical for each project area, drag the blue button to the left or right. Please note that the cross-sections are typical for each project area and may not be representative of the entire corridor length.
Area A: SW Andover St – SW Alaska St
Design updates between: Genesee and Brandon
- Pavement restoration was reduced on Delridge Way SW between SW Andover St and SW Genesee St to avoid tearing up new concrete when Sound Transit builds the Delridge Link light rail station
- Removed median from SW Andover St to SW Dakota St to avoid the need to remove new medians, landscaping, and irrigation when Sound Transit builds the Delridge Link light rail station
Area B: SW Alaska St – SW Hudson St
- Added an emergency median cut-thru for Seattle Fire Department in the long island north of SW Hudson St
- Included median islands to prevent tree roots from growing into existing Seattle Public Utility (SPU) pipes
Area C: SW Hudson St – SW Juneau St
Area D: SW Juneau St – SW Myrtle St
Area E: SW Myrtle St – SW Holden St
- Added southbound protected bike lane with buffer
- 24/7 RapidRide transit only lane in select locations
- Speed limit reduced to 25 mph in compliance with citywide Vision Zero initiative to lower arterial speed limits
- Painted curb bulbs added on the east legs of 21st Ave SW and SW Croft St at Delridge Way SW to reduce the intersection footprints and improve pedestrian safety
- A northbound left-turn lane into SW Webster St and a small refuge island for eastbound Webster traffic turning left onto Delridge Way SW
- Moved the northbound RapidRide station at SW Thistle St from the northeast corner to the southeast corner of the intersection to avoid a large existing Seattle City Light (SCL) vault
Area F: SW Holden St – SW Cambridge St
- The northwest corner of this intersection will include a protected bike lane raised to curb height along the island to improve visibility for people biking.
- Planter strip added along the south side of SW Barton St at the Delridge Way SW intersection to add more protection for the sidewalk.
- Altered tree planting locations in the proposed median islands to prevent tree roots from growing into existing Seattle Public Utility (SPU) pipes.
- Added water quality facilities at SW Holden St and SW Thistle St where existing facilities are undersized and do not meet code.
Corridor wide design updates:
- Changed concrete curbs separating northbound and southbound traffic with painted stripes at most intersections to allow better navigation of emergency vehicles and improve emergency response routing.
The Delridge Way SW - RapidRide H Line project includes a variety of design updates to the project corridor, including pedestrian, parking, transit, bike, paving, water and sewer details. Click on the images below to enlarge the detail maps.
The RapidRide H Line project is currently in construction with a variety of different demolition, paving, storm work, and other activities happening along the corridor.
