Broadway and John Street Signal

Updated: October 19, 2021

What's happening now?

The project was originally planned to be built in 2021, but we need additional time to coordinate the design with King County Metro and nearby utilities. Construction is now planned to start in early 2022. 

Thank you to all who participated in the community prioritization process and provided feedback on initial project designs! 

Project Overview

The project, located on Capitol Hill at the intersection of Broadway and E Olive Way/E John St, aims to address a crash pattern with left turning drivers. We'll rebuild the traffic signals to have "protected left turns" where left turning drivers have the red while people walking and biking as well as oncoming traffic have the green. This will reduce collisions and better organize the intersection. 


  • Rebuild the traffic signals on the east and west legs of Broadway
  • New left turn pockets and separated signal phases on E Olive Way and E John St
  • Improving transit efficiency by restricting westbound left turns to transit only (from John to Broadway) 


  • Better organizes the intersection
  • Addresses persistent collision patterns at this intersection:
    • Defined approach lanes – helps drivers get into the proper lane at the intersection and reduces the instances of two vehicles driving in the same lane
    • Improves sight lines – makes it easier for drivers, people walking, and people biking to see each other at the intersection
    • Separate left turn phases – reduces opportunities for turning drivers to conflict with oncoming traffic and/or pedestrians in the crosswalk
  • Upgrades old traffic signals to new standards

Project Background

In 2019, the Broadway and John St Signal project was one of 15 projects selected by the Levy to Move Seattle Oversight Committee to be funded through SDOT’s Neighborhood Street Fund Program. Neighborhood Street Fund is a city program, running on 3-year cycles, that enables neighbors to propose and help prioritize transportation-related projects that are then built by the Seattle Department of Transportation.
