On Nov. 4, 2008, voters of the Central Puget Sound region approved a historic Sound Transit 2 ballot measure that will provide an alternative to rising gas prices and greenhouse gas emissions. The plan adds regional express bus and commuter rail service while building 36 additional miles of light rail to form a 55-mile regional system.
