The Board's role

Sound Transit is governed by an 18-member Board of local elected officials. The Board:

  • Establishes policies and gives direction and oversight
  • Shapes Long-Range Plan and ballot measures
  • Makes project decisions at critical milestones
  • Approves major contracts

The Board meets regularly in meetings that are open to the public.

Sound Transit 3 connects region's cities with mass transit

In November, 2016 regional voters approved Sound Transit 3 (ST3). This 25-year mass transit expansion plan adds 62 miles of new Link light rail; brings bus rapid transit service north, east and south of Lake Washington; increases Sounder train capacity on the south line; and improves parking and access to stations throughout the system.
