PROJECT UPDATE: Arterial Crossings Construction Work in May

Work to improve arterial crossings along the West Seattle Neighborhood Greenway will take place at the intersection of 30th Ave SW and SW Barton St on the weekend of May 4-5, and at 34th Ave SW and SW Morgan St the week of May 20. 

What work will take place?

  • 30th Ave SW and SW Barton St: Cutting bike detection loops and installation of overhead signs
  • 34th Ave SW and SW Morgan St: Installation of new pedestrian refuge islands

What are the potential impacts?

  • Noise
  • Dust
  • Construction crews
  • Traffic control
  • Possible impacts to pedestrian access

PROJECT UPDATE: West Seattle Greenway Phase 1 heading for completion as soon as this summer!

The following elements of Phase 1 are now complete:

  • Speed humps have been installed along the entire Phase 1 route (along 30th Ave SW and 34th Ave SW between SW Roxbury and SW Graham streets)
  • New pedestrian refuge island has been installed at SW Trenton St. The island is designed to reduce traffic speeds and volumes, and to encourage more people to walk and bike. 

What’s next?

The following elements are expected to be completed as soon as summer 2019:

  • Crossing improvements at the following key intersections:
    • SW Barton St and 30th Ave SW
    • SW Thistle St and 30th Ave SW
    • SW Holden St and 34th Ave SW
    • SW Morgan St and 34th Ave SW
    • Sylvan Way SW and SW Holden St
  • Installation of signage to direct people along the greenway route

This first phase of the West Seattle Greenway will wrap up as soon as summer 2019. Thank you for your input, feedback, and patience throughout this process. 

We expect to complete the High Point Loop (indicated on the route map) in the next year. This segment will include:

  • Speed humps
  • Traffic calming
  • Pavement and sidewalk repair

Phase 2 will include a new crossing signal at 35th Ave SW and SW Graham St. Updates on the final design and timeline are coming soon. Stay tuned!

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 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, our proposal includes:

  • walk/bike crossing signal
  • push button activation
  • improved lighting
  • crosswalks
  • elimination of certain high-risk turning movements

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 will begin in summer 2018.


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.
