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 Board approves 15-year expansion package, sends to November 2008 ballot: The Sound Transit Board today unanimously approved placing a 15-year mass transit package on the November ballot. The plan rapidly increases express bus and commuter rail service and creates a 53-mile regional light rail system — all with a lower price tag, faster delivery dates and more public accountability than last year’s roads-and-transit package.

New 15-year mass transit expansion package offers further rail extensions and faster completion dates: The 15-year plan represents a new alternative for a mass transit ballot measure, alongside 12- and 20-year options identified in April. The new plan responds to public input received in May and June that included strong desire to see light rail extended further north and south than was proposed in the 12-year options.
