23rd Ave E Vision Zero Project

Enhancing safety and mobility

June 21, 2017

What's happening now

Thank you to all who attended our public meetings this past spring and shared your feedback with us in-person and online.

Stay tuned for upcoming events this summer, where we’ll share what we heard in our outreach and suggest near-and long-term alternatives for the corridor.

Project Overview

We're launching the 23rd Ave E Vision Zero Project to enhance safety and mobility on 23rd Ave E and 24th Ave E between E John Street and E Roanoke Street. This important street provides access to the Montlake neighborhood, SR 520, the Montlake Bridge crossing into north Seattle and transit.

Click to view larger Project MapThe 23rd Ave corridor is currently four to five lanes with peak hour parking restrictions in some locations. There is a significant curve in the road where 23rd Ave E meets Turner Way and becomes 24th Ave E. A steep hill south of Boyer Ave E contributes to people driving faster than the posted speed limit.

Thousands of drivers travel at speeds higher than 40 mph, where the posted speed limit is 30 mph. Speeding occurs frequently on northbound 24th Ave E, on the downhill portion of the street. The highest speeds were recorded at E Prospect Street where 85% of drivers travel at 42 mph. In the Montlake Business District, most people travel nearly 7 mph over the posted speed limit.

Vision Zero is our plan to end traffic deaths and serious injuries by 2030. Ninety percent of serious traffic crashes occur on arterial streets like 23rd and 24th Ave E. We are committed to enhancing safety for everyone that uses this corridor. In the last three years, there have been 134 total collisions on this portion of the corridor. These crashes caused 63 injuries to people walking, biking and driving. There has been one fatal collision on this street in the last decade.

We're also working to make it easier to walk and bike around the Montlake Neighborhood and partnering with WSDOT to help manage traffic during SR 520 construction.

What to expect

Based on technical analysis, transportation plan recommendations and public input, project features may include:

  • New pavement or pavement repair
  • Redesigning the street
  • Traffic calming
  • Sidewalk repair and new curb ramps
  • Crossing improvements
  • New traffic signals
  • Transit speed and reliability elements
  • Business access improvements
