West Seattle Neighborhood Greenway

Updated October 6, 2021

What's Happening Now?

Construction is almost done on Phase 2 of the West Seattle Neighborhood Greenway!

Have you already used the greenway? Please tell us what you think by email. We'd love to hear from community members already using the West Seattle Greenway to understand how it's working so far.

Neighborhood street construction: We are done with construction on neighborhood streets. This included building speed humps, adding stop signs at intersections, and adding directional signs along the greenway route.

35th Ave SW and SW Graham St construction: At the 35th Ave SW and SW Graham St intersection, we have installed the bike lane markings, crosswalks, directional signs, and diverters that restrict turns for people driving. See photos below for what the intersection looks like now.

The final work at this intersection includes getting electrical power to the traffic signal and installing the detection in the street for recognizing when a person biking is waiting at the traffic light. Due to construction crew capacity, as well as COVID-19-related supply delays, we expect to complete this work in mid-October. The schedule is subject to change. 

We are keeping all sides of the intersection open until we start work again. When we do begin work, we'll need to close both sides of the intersection a final time as we complete the remaining work. The remaining work is expected to take 4-5 days.

We will keep you updated as work continues in this area and send a final note when construction is complete. Thank you for your patience and understanding while we install the West Seattle Neighborhood Greenway in your neighborhood. 

Project Description 

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.
