12th Avenue Vision Zero Project

Last updated: October 29, 2018

Project Overview

12th Avenue S is a crucial bike, pedestrian, and transit corridor through some of the densest and most diverse parts of the city, connecting Little Saigon to Beacon Hill. As Seattle grows and demand on the street increases from everyone from residents of Yesler Terrace to businesses and patrons in Little Saigon to bicyclists arriving from Beacon Hill or the Mountain to Sounds Trail, it is important to ensure that 12th Ave S serves as a safe and accessible route for people of all ages and abilities. In partnership with neighboring communities, SDOT is committed to identifying and investing in safety and mobility improvements along the corridor.

There has been more than 15 total combined vehicle and pedestrian and vehicle and bicyclist collisions reported at the intersection of 12th Ave S and S Weller St, 24 total combined collisions between S Weller St and S Charles St, and 5 combined collisions at the intersection of 12th Ave S and S Charles St between 2004 and 2017.

Together with the community and the people who visit the neighborhood, we will determine the specific nature and design elements of the necessary changes. We’ll consider traffic calming, signal modifications, and pedestrian and bicycle safety enhancements. See below for project map and more detail.

Project Details

This project will:

  • Install safety enhancements for people walking and biking at S Weller St and S Charles St
  • Reduce speeds of vehicular traffic on 12th Ave S at the Jose Rizal Bridge
  • Improve the walking and bicycle connections along and across 12th Ave S
  • During the initial project planning phase, we will analyze traffic data and safety information, hear community concerns, and review SDOT's modal plan recommendations for walking, biking, transit and frieght.

Possible elements of the project include:

  • crosswalk and signal improvements at the intersections of Pike, Spring, Marion, Spruce, Fir, King, and Weller
  • implementing protected bike lanes, which include a buffer with white plastic posts
  • installing left-turn lanes

Outreach & Schedule

We’re currently reviewing existing conditions and gathering community input on potential strategies. This summer we’ll develop potential street design concepts to present and gather feedback to inform the final design.
