Project overview
Making Delridge Way SW a better street
RapidRide H Line is designed to meet the following goals:
Provide transit service to support employment growth
By 2035 RapidRide H Line will serve 187,000 employees in the project neighborhoods
Improve transit travel time and reliability throughout the corridor
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

- Translated phone calls to self-identified businesses with language needs
Bus stops
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.
Final design improvements
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
Design updates
- 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
Design updates:
- Landscaped median to replace center turn lane

Area D: SW Juneau St – SW Myrtle St
Design updates:
- Added southbound protected bike lane with buffer
- 24/7 RapidRide transit only lane in select locations
View the channelization plans (3.1 MB PDF) and the paving plans (5.5 MB PDF) for this area.
Area E: SW Myrtle St – SW Holden St
Design updates:
- 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
Design updates:
- 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.

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.
