35th Ave SW Road Safety Corridor Project

Updated: July 2024

Since 2015, we have reviewed conditions along 35th Avenue SW and collaborated with the community to find solutions to safety challenges. This project worked to address one of the top streets in the city for serious crashes and will enhance access to along and across the street and to destinations like parks, libraries, schools, and shopping. The project also contributed to the completion of the West Seattle Neighborhood Greenway that created all ages and abilities connections to destinations like Camp Long, the West Seattle Junction, and numerous schools and parks along the route.

  • After a Phase 1 redesign, speeding dropped by an average of 42%.
  • At the end of July 2018, we began to implement operational changes at 35th Ave SW and SW Juneau St.
  • Phase 2 of this project installed a new signal and pedestrian crossing at 35th and SW Dawson St, channelization improvements and turn restrictions at 35th and SW Juneau St, new turn signals at 35th and SW Barton St, pavement repair, and more than two dozen ADA curb ramps throughout the project area.

Project Goals

  1. Implement safety measures to prevent serious or fatal collisions
  2. Provide predictable and efficient travel for people driving and taking transit
  3. Enhance pedestrian access to key destinations along the street

Community Outreach & Engagement

We sent out a neighborhood flier in July 2016 and held an open house in August 2016. Outreach and design concluded in 2016, and then the safety corridor work, including the new signal, will be done in 2019.


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.
