West Seattle Neighborhood Greenway

What's Happening Now?

Construction of Phase 2 of the West Seattle Greenway began in late February 2021. It will be completed as early as mid-July 2021.

Week of 4/19

Construction is starting at 35th Ave SW and SW Graham St Intersection as early as Wednesday, April 21. Expect a lot of construction activity at the 35th Ave SW and SW Graham St intersection as SDOT crews build the changes, shown below

  • Typical weekday work hours of 7 a.m. to 5 p.m., Monday through Friday
  • Occasional weekend work, hours of 7 a.m. to 5 p.m., Saturday and Sunday
  • Temporary on-street parking restrictions, with "No Park" signs placed in advance
  • Parking restrictions to allow space for work and equipment
  • Driveway closures when crews are prepping and building the sidewalk in front of driveways
  • Flaggers directing people driving and biking around the work
  • Lane reductions near the work area for people driving
  • Detours around the work area for people walking and driving
  • Noise, dust, and vibrations during work hours
Construction impacts on neighborhood streets: The impacts on the neighborhood streets will be minimal. When work is about to begin on your street, you will see "No Park" signs placed in advance. 
  • On neighborhoods streets, we are installing:
    • Speed humps to calm traffic
    • Signs to indicate speed humps
    • Signs and pavement markings to help people find their way along the Greenway
    • Stop signs on the side streets at intersections 
  • Approximate locations of speed humps (19 total) for West Seattle Greenway Phase 2 are below. View this project design to see the exact location. Speeds humps will start being installed as early as Thursday, March 11 and take a few days to complete. Once they are done, the "No Park" signs will be removed.  
    • On 42nd Avenue SW
      • 1 - Just south of the intersection with SW Edmunds St
      • 2- Before and after intersection with SW Hudson St
      • 2- Before and after intersection with SW Dawson St
      • 2 - Before and after intersection with SW Brandon St
      • 1 - Just north of intersection with SW Findlay St
    • On SW Findlay St
      • 1- Just west of intersection with Fauntleroy Way SW
      • 1- Just west of intersection with 38th Ave SW

We will work with neighbors and the construction contractor to minimize construction impacts as much as possible.

Project Overview

We’ve been working with West Seattle since summer 2016 to select a route for a new north-south neighborhood greenway. Hundreds of people gave feedback via an online survey, public events, and conversations with the project team. We heard requests for a neighborhood greenway with:

  • improved connections to the Junction and Westwood Village, as well as parks and schools
  • fewer hills to climb
  • slower speeds
  • safer crossings at busy streets like 35th Ave SW

Project Elements

West Seattle neighborhood greenway study area:

  • During phase 1 of outreach, we invited people to learn about and share their preferences on several route options.
  • Greenway route options at the north end included the Alaska Junction business district, Camp Long entrance at SW Dawson St, and the existing Delridge greenway east of the West Seattle Golf Course at SW Brandon St.
  • Our proposal for the south end included the greenway route going north-south on 30th Ave SW, 34th Ave SW, and 36th/37th Ave SW.

You can see the routes we studied and learn more about what we heard in the first phase of outreach here.

New crossing signal: 35th Ave SW and SW Graham St

There have been 2 traffic fatalities in recent years at this intersection—a person walking and a person biking. The community's reaction to these crashes and the response we received to our earlier survey have demonstrated a desire for a change at this location so that it feels safer for people, is better lit, and creates a more inviting connection to the new multifamily and retail construction on the corner. We think this intersection improvement can make it more family-friendly and dynamic so people want to visit, shop and play, nearby, no matter how they get around.

Specifically, the changes include:

  • Adding a push-activated crossing signal for people using the Greenway. When activated, the signal will turn red for people driving on 35th Ave SW.
  • Removing high-risk turning movements:
    • People driving on SW Graham St (eastbound and westbound) will not be able to turn left onto 35th Ave SW or to drive straight through to the other side of SW Graham St. They can only turn right onto 35th Ave SW.
    • People driving southbound on 35th Ave SW will not be able to turn left or right onto SW Graham St. They will need to drive around one block to access SW Graham St.
    • People driving northbound on 35th Ave SW will not be able to turn left onto SW Graham St. They can still turn right onto SW Graham St.
  • Building new crosswalks
  • Improving lighting at the intersection
  • Painting green markings for people biking to cross the intersection
  • Building speed humps on SW Graham St approaching the intersection

Project Description

The West Seattle Neighborhood Greenway project came from city planning efforts and community requests. The Bicycle Master Plan (BMP) calls for neighborhood greenways primarily located on 34th Ave SW, as well as 36th Ave SW / 37th Ave.

We’ve been engaging with people in West Seattle to help us design a neighborhood greenway that connects residents with schools, parks, local businesses, and the greater transportation network. The new greenway will bring affordable, active transportation options for all ages and abilities.

See the map above for the most promising route, which was selected after listening to the community and reviewing existing transportation plans and traffic data.

The north route connects to the Junction and the south route combines what people liked about both 34th Ave SW and 30th Ave SW. The selected route avoids the steepest hills and prioritizes streets with lower vehicle speeds and traffic volumes. It connects people to popular business districts, schools, parks, transit, and Seattle’s growing bike network.

What's a Neighborhood Greenway?

Neighborhood greenways are safer, calmer residential streets for you, your family, and neighbors. We make people walking and biking the priority.

Neighborhood greenways can include:

  • 20 mph speed limit signs
  • speed humps to calm traffic
  • stop signs for side streets crossing the neighborhood greenway
  • signs and pavement markings to help people find their way
  • easier crossings of busy streets with crosswalks, flashing beacons, or traffic signals


Approved by voters in 2015, the 9-year, $930 million Levy to Move Seattle provides funding to improve safety for all travelers, maintain our streets and bridges, and invest in reliable, affordable travel options for a growing city.


The first phase of outreach started in summer 2016 and concluded in December 2016. The next phase has begun and will wrap up in July. Construction of phase 1 of the greenway began in summer 2018. Construction of phase 2 begins in early 2021. 


We are committed to building a productive, inclusive, and collaborative relationship with all who live, work, or travel in the project area. Please contact us with any questions.
