Overview
The West Seattle Link Extension will provide fast, reliable light rail connections to dense residential and job centers in the SODO, Delridge, and West Seattle neighborhoods. The West Seattle Link Extension is part of the regional transit system expansion approved by voters in November 2016. The West Seattle Link Extension:
- Adds 4.1 miles of light rail service from SODO to West Seattle's Alaska Junction neighborhood.
- Includes four new stations from SODO to Alaska Junction.
- Start of service scheduled for 2032.
Current project status
The Sound Transit Board selected route and station locations for the West Seattle Link Extension Project in October 2024, following review of environmental documents and years of public feedback. Sound Transit’s federal partner, the Federal Transit Administration (FTA), issued a Record of Decision (ROD) on April 29, 2025. This decision is the final step in wrapping up the planning and environmental review process under the National Environmental Policy Act (NEPA). Sound Transit will advance the West Seattle Link Extension Project to final design.
