Overview

The West Seattle and Ballard Link Extensions will provide fast, reliable light rail connections to dense residential and job centers throughout the region.

These two separate Link extensions are part of the regional transit system expansion approved by voters in November 2016.

Current project status

The Sound Transit Board has identified preferred alternatives and other alternatives to study in a Draft Environmental Impact Statement (EIS). The Draft EIS is the next step in the environmental review process, where we will evaluate potential impacts and benefits of the alternatives on the natural, built and social environment, and identify potential mitigation measures. The Draft EIS is anticipated to be released in early 2021 for public review and comment.
