Rainier Ave S + S Henderson St Improvement Projects

August 2026

We’re making Rainier Ave S as well as S Henderson St better for people using the streets, sidewalks, transit, and public spaces. These projects focus on maintaining and modernizing the streets to make it safer and more comfortable for you no matter how you travel. Our goals are to improve the infrastructure on and below the road to make it easier to walk, bike, and cross the street. The Rainier Ave S + S Henderson St Improvement Projects also support speed and reliability improvements for transit and will be coordinated with King County Metro’s future upgrade of the Route 7 to the RapidRide R line. This project is one of the largest corridor investments in the Seattle Transportation Levy. 

These projects are in early planning stages. We will update this webpage and the community in the coming months with more information. Sign up for our listserv to receive project updates.
