23rd Ave E Vision Zero Project
Enhancing safety and mobility
June 21, 2017
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.
The 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.
What to expect
Based on technical analysis, transportation plan recommendations and public input, project features may include:
Summer 2017: Share what we heard to date and suggest possible near-and long-term alternatives
Fall 2017: Share near-term and long-term safety improvements
2018: Construction of short-term safety improvements
2019/2020: Implement corridor-wide improvements
These projects are funded by the 9-year Levy to Move Seattle, approved by voters in 2015.
