Project

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.

• West Seattle Link Extension
  • Adds 4.1 miles of light rail service from SODO to West Seattle's Alaska Junction neighborhood.
  • Includes 4 new stations between SODO and Alaska Junction.
  • Start of service scheduled for 2032.

Current project status

Sound Transit and the Federal Transit Administration published the West Seattle and Ballard Link Extension Draft Environmental Impact Statement (EIS) for public comment on Jan. 28, 2022, followed by a 90-day public comment period. The WSBLE Draft EIS evaluated potential impacts and benefits of the alternatives on the natural and built environment, and transportation systems and identified potential mitigation measures.  

In July 2022, after reviewing the WSBLE Draft EIS and the comments from Tribes, the public and agency partners, the Sound Transit Board identified the preferred alternative for the West Seattle Link Extension (WSLE) on July 28, 2022, and requested further study for the Ballard Link Extension (BLE). Read more about the Sound Transit Board’s action in the Board Motion. Check out the preferred alternative for the West Seattle Link Extension on the Online Open House.   

The extensions were initially on the same environmental review timeline. However, given additional environmental review needed for project refinements for BLE resulting from the Sound Transit Board action in March 2023, environmental review for the two extensions will now proceed on different timelines.   

WSLE will proceed to a Final EIS, which is anticipated to be published in 2024, while a new Draft EIS will be completed for BLE to reflect action by the Sound Transit Board in March 2023. The BLE alternatives will be updated, including analysis of the preferred alternative, as well as other refinements and alternatives identified in March 2023 board motion.  

What can I expect as a project neighbor?

If you have any questions or you would like to set up a meeting to learn more, contact the project team at westseattlelink@soundtransit.org. 

• The Sound Transit Board will make a final decision on routes, stations and the project to be built after a final EIS is published for WSLE.
