Rainier Avenue S Corridor Improvements
Last updated: July 12, 2017
In 2014, we launched a collaborative process to review conditions along Rainier Avenue S. As safety is our number one priority, we are committed to preventing crashes and improving safety for all travelers. This project is part of Seattle’s Vision Zero program to reach zero traffic fatalities or serious injuries by 2030.
Project Need: Over the last 10 years, there have been nearly 3,600 total collisions along Rainier Ave S. On average, there is 1 crash per day that takes 45 minutes to clear. Rainier has almost double the number of crashes per mile compared to Aurora Ave N and Lake City Way NE even though they carry almost twice the vehicle volume.
Most people were driving at 38 mph, where the posted speed limit was 30 mph. Speeding increases the severity of crashes and makes it more difficult for people driving to recognize possible hazards.
In 2015, one mile of Rainier between S Alaska St and S Kenny St was redesigned from four to three lanes. This project successfully improved safety along Rainier Ave S in Columbia City and Hillman City. Highlights from our evaluation report include:

Measures being considered include: traffic calming, traffic signal upgrades, pavement repair, and pedestrian and bicycle safety enhancements. We’ll also develop educational materials that address behavioral issues like speeding, distracted driving, and impaired driving and perform area-specific outreach to help prevent crashes.
