Welcome to the Sound Transit system expansion website, where you can help Sound Transit tackle challenging questions about the future of our region. Increasing traffic is only making it harder to travel from place to place. Studies show that by 2030, rush-hour could last all day in many places.

Sound Transit has identified new options for a smaller and quicker package of light rail, commuter rail and regional express bus expansions that would be completed in 12 years. Your voice will help shape the Sound Transit Board’s decision on the timing of a mass transit expansion measure and whether to move forward with a 12-year or a 20-year package.
