Building fast, reliable transit
System expansion
With voter approval in 1996, 2008 and 2016, Sound Transit is building the most ambitious transit expansion in the country.
Long-term affordability
Delivering the ST3 vision
Sound Transit is working to close a $34.5 billion future funding gap projected through 2046 to deliver what's outlined in the voter-approved Sound Transit 3 program. ST3 includes light rail extensions to West Seattle, Ballard, Tacoma, and Everett, new service between South Kirkland and Issaquah, and much more.
Sound Transit Board
The Sound Transit Board of Directors makes key decisions about our system by adopting budgets, identifying alternatives to include in environmental review, selecting preferred alternatives, and establishing baselines for project scope, schedule, and budget.
- Review Board documents, including meeting minutes, motions, and resolutions.
- Sound Transit Board and Committee meetings are streamed live and recorded. Following meetings, recordings are uploaded to Sound Transit's YouTube account. Meetings recorded before July 2024 can be viewed on PhotoShelter.
