S Jackson St Vision Zero Safety Corridor

Updated: January 2026

About the Project 

The S Jackson St Vision Zero Safety Corridor Project aims to make S Jackson St safer for everyone. The project spans several neighborhoods, including Chinatown-Internacional District, Pioneer Square and Little Saigon, covering S Jackson St between Alaskan Way to Rainier Ave S.

This area has a high number of crashes, including serious ones. Our goal is to make this area safer for people walking, biking, taking transit and driving by investing in transportation safety improvements. Common treatments could include:

• Improving visibility at intersections and pedestrian crossings.
• Installing safety improvements at traffic signals. 
• Adding traffic calming treatments.

S Jackson St connects important neighborhoods like the Chinatown-International District, Little Saigon, and Pioneer Square. It also links key transportation services such as the First Hill Streetcar, the Chinatown-International District Link station, and King Street Station. 

Data from June 2024 shows that about 3,200 vehicles travel the corridor during morning and evening rush hours, along with high volumes of buses, people walking, and biking.

S Jackson St is a priority for the Vision Zero program, which aims to end traffic deaths and serious injuries, and create a culture of care and dignity for everyone who uses Seattle’s streets.  

Project Goals 

• Base solutions on data: Use collision and traffic data to implement safety improvements where they're needed most.
• Collaborate with the community: Work closely with neighborhoods, businesses, and residents to understand their needs and build project awareness.
• Coordinate with transit partners: Collaborate with Sound Transit and King County Metro to align this project with ongoing transit work. 

By working together, we can make S Jackson St safer and improve mobility for everyone.

Project area

The S Jackson St Safety Corridor extends from Alaskan Way S to Rainier Ave S, and we will prioritize safety treatments along this corridor where they are most needed.

Project Schedule

• 2025 to early 2026: We’re analyzing traffic data and hearing from the community about their experiences. All of this will help us define our design options.
• Mid-2026: We’ll bring together collision and traffic data for S Jackson St, technical input from the team, and what we heard from the community to guide our design work.
• Late 2026 through 2029: We’ll move into construction and keep the community informed with regular updates about schedule, progress, and expected impacts.

Construction schedules are also subject to change and depend on factors such as weather and availability of crews and materials.
