Welcome
The West Seattle and Ballard Link Extensions will provide fast, reliable light rail connections to dense residential and job centers throughout the region and add a new Downtown Seattle light rail tunnel to add more capacity for the entire regional system.
Learn about the Level 3 "end-to-end" options
Since the project’s kick-off, we’ve been collecting public feedback to develop, study and narrow down alternatives. The alternatives development process for this project consists of three phases, where the most promising alternatives at each level have been carried forward to be studied in greater detail based on technical analyses, advisory group recommendations and community feedback. Level 3 evaluation includes three end-to-end alternatives, plus a few design options. Click the button below to view maps and information about these alternatives.

What is Light Rail?
Link light rail is an electric train rapid transit system connecting widely-spaced stations throughout the region. Because it operates on its own track, Link offers fast and reliable travel times regardless of weather or traffic. The Link system currently serves a 22-mile line between the University of Washington and Angle Lake, south of SeaTac Airport. With voter approval of funding for system expansion in 2008 and 2016, the light rail system will grow to 116 miles with new stations opening every two to six years.
