At its June 26 meeting, the Sound Transit Board of Directors identified a preferred alternative for the Tacoma Dome Link Extension. The preferred alternative includes: 

• South Federal Way Segment: SF 99-West alignment refined to be on the east side of SR 99 in Milton with the SF 99-352nd Station.
• Fife Segment: Fife I-5 alignment with Fife Station.
• Tacoma Segment: Close to Sounder alignment with the Portland Avenue Station and Close to Sounder Station.

The Board considered the findings from the Draft Environmental Impact Statement (EIS), comments received on the Draft EIS, additional analysis in response to Draft EIS comments, Sound Transit’s Equitable Engagement Tool, recommendations from staff, and other information before identifying the preferred alternative. Read more about the Board’s action in our press release and the Board Motion.

The identification of a preferred alternative is not a final decision on the project to be built. This action indicates where the Board is leaning based on the information available at this time. The Board will make a final decision on the project that will advance into Final Design after evaluating the preferred alternative and other alternatives in the Final EIS, expected no earlier than 2027.
