Rainier Ave S and S Jackson St. Safety Enhancements

Updated: April 18, 2024

This project is complete!

The Rainier Ave S and S Jackson St. Safety Enhancements project was completed in April, 2024.

What’s happening now?

We are happy to share the completion of our Rainier Ave S and S Jackson St. Safety Enhancements project. Crews finished installing a protected left turn phase and other signal improvements.

The protected left-turn phase allows westbound turning vehicles to make a left turn at this intersection without conflicting with oncoming eastbound traffic. During this phase, indicated by a green left-turn arrow on the traffic signal, vehicles in the turning lane have the right-of-way while oncoming traffic is stopped by a red light. This improves the safety of left-turning vehicles by preventing collisions with vehicles coming from the opposite direction.

Project Overview

The intersection of Rainier Ave S and S Jackson St. is a busy intersection located in the Jackson Place and Little Saigon neighborhoods. During peak periods, long queues develop westbound on S Jackson St. for left-turning vehicles to access southbound Rainier Ave S.

The westbound left turn movement is currently permissive and turning vehicles must negotiate with oncoming traffic.

The project will add a protected left turn phase and other signal improvements. Additional signs and markings may be considered during design to improve traffic flow and safety at the intersection.
