Project Overview

In 2019, the 51st Ave S and Renton Ave S Traffic Safety Enhancements was one of 15 selected by the Levy to Move Seattle Oversight Committee to be funded through SDOT's Neighborhood Street Fund (NSF) Program.

The concept funded by the Levy Oversight Committee aims to build and accomplish the following:


  • New intersection with full traffic signal to better direct travelers through and around the area
  • Redesigned concrete island for improved safety and visibility for people walking and biking through the intersection
  • New flashing beacons, curb bulbs, sidewalk level path, cross walks, and stop lines to shorten crossing distances, increase visibility, improve accessibility, and enhance the safety of people walking for people driving
  • New bike ramps, bike box, and green pavement markings for enhanced visibility, comfort, and safety of people biking for people driving


Concept design for 51st Ave S and Renton Ave S Traffic Safety Enhancement. Features include new traffic signals, wider sidewalks, new bike facilities, and new curb bulbs and curb ramps.

Project Background

The project, located at the intersection of51st Ave S, Renton Ave S, & S Roxbury St, is a skewed four-way, stop-controlled intersection with an additional intersection with S Roxbury St just south of the main intersection. There have been over 240 collisions at this intersection and adjacent areas since 2004 and community members have identified notable congestion during peak hours.

In late 2008, the Southeast Transportation Study proposed replacing the intersection with a new double roundabout with construction anticipated for 2010. The project failed to advance soon after as the rising cost of real estate made it infeasible to acquire land for the proposed roundabouts. This new Neighborhood Street Fund concept proposal aims to improve safety and provide better access to the Rainier Beach light rail station. 

Note: funds not used for this project will be returned to the NSF program budget.
