Light Rail Projects
About the Expansion
In the coming years, Sound Transit will build new light rail lines from the Chinatown/International District to Ballard and from SODO to West Seattle. This expansion will include a new transit tunnel under Downtown and two water crossings. It is the largest transit investment in our city’s history.
In addition to the new lines, Sound Transit will also build three new stations along existing routes. These include:
• Pinehurst Station
• Graham Street Station
• Boeing Access Road Station
