Tacoma Dome Link Extension project map

Light Rail is coming to the South Sound

Get introduced to our project and see how we're evaluating station and route options. View video.


The Tacoma Dome Link Extension connects Pierce County to the regional light rail network, including direct access to Sea-Tac Airport and downtown Seattle, with stations at Tacoma Dome, East Tacoma, Fife and South Federal Way. The Tacoma Dome station serves as a multi-modal transit hub, with transfer options to and from Sounder service, Tacoma Link, Amtrak and Pierce Transit and Sound Transit buses.

Per the voter-approved Sound Transit 3 plan, the representative project for the Tacoma Dome Link Extension connects Federal Way to Tacoma on a primarily elevated guideway with a new rail-only fixed span crossing the Puyallup River. The project also includes an operations and maintenance facility for the south corridor. Agencies will determine the location for this facility later in the project's development.
