Sound Transit 3


The Sound Transit 3 Plan (ST3) will include projects that will expand the regional transit system throughout King, Pierce, and Snohomish Counties.  The plan, which was approved in 2016, adds 62 miles of light rail as well as providing additional bus rapid transit (BRT) lines, and expanding the capacity and service area of the Sounder rail line.  Within the Seattle city limits, the ST3 plan includes 12 miles of new light rail lines with 14 stations to service West Seattle, SODO, Downtown, South Lake Union, Uptown, Interbay and Ballard neighborhoods.  The plan also includes two infill stations, NE 130th St in North Seattle and S Graham St Station in Rainier Valley, along the existing light rail alignment.   The West Seattle to Downtown light rail line extension is projected to open in 2030, while the Downtown to Ballard extension will open in 2035.
