Tacoma Dome Link Extension

Project Highlights


  • Link light rail

Start of service:

Targeted for 2030


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

Per the voter-approved ST3 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 operation and maintenance facility, location to be determined.
