The Tacoma Dome Link Extension will add nearly 10 miles to our regional light rail system via mostly elevated tracks between Federal Way and Tacoma. This project includes four new light rail stations in the South Federal Way, Fife, East Tacoma/Portland Avenue and Tacoma Dome areas.

These stations will also provide connections to other regional transit services like Sounder, Tacoma Link, ST Express, King County Metro, Pierce Transit, Intercity Transit and Amtrak.

Stations will feature pickup and drop-off zones and provide convenient access for pedestrians, cyclists, and riders arriving on paratransit and other modes. The future South Federal Way and Fife stations will each offer approximately 500 parking spaces.

Benefits of the TDLE

When Tacoma Dome Link service starts in 2032, it will offer fast and frequent travel to destinations across the region, including: 

  • South Federal Way to Tacoma Dome Station in 20 minutes
  • Fife to Tacoma Dome Station in 6 minutes
  • Tacoma Dome Station to Sea-Tac Airport in 35 minutes

Current project status

We received public comments on the TDLE project during our Environmental Impact Statement scoping period, April 1 to May 1, 2019. We compiled the public feedback from this official comment period into a Scoping Summary Report.

On July 25, 2019, the Sound Transit Board of Directors identified possible route and station locations — formally called a "preferred alternative" and "other alternatives" — to study in the Draft Environmental Impact Statement. A Draft EIS analyzes and documents a project's potential impacts to the natural and built environment, and it proposes ways to mitigate unavoidable impacts. 

In this current phase, we'll continue with more conceptual design work, including refinements to route and station alternatives. You can view the latest maps of the alternatives under consideration by segment area here.

In addition to its financial impacts, the COVID-19 pandemic also affected Sound Transit’s ability to advance environmental review processes, both internally and with our planning partners. Consequently, we now expect to publish the TDLE Draft EIS in 2022.

Our process for providing public review and comment opportunities on project environmental documents has not changed; when we publish the Draft EIS, we’ll also invite the public to review and make formal comments. We’ll share the news through our digital channels, and we’ll also mail postcards to residents, businesses and property owners before the public comment period.

Questions or comments before then? We're always here to help. You can contact the project team at tdlink@soundtransit.org.

We encourage you to sign up for project email updates for all the latest news as the TDLE develops.

What can I expect as a project neighbor?

  • If you're a resident, business or property owner near a potential TDLE route or station, signing up for email updates is the first step to ensuring you're always up to speed on the project. If you have any questions or you'd like to set up a meeting to learn more, contact the project team at tdlink@soundtransit.org.
  • The Draft EIS will evaluate possible property impacts in detail. You'll have opportunities to comment on those findings after we publish the Draft EIS in 2022. The Sound Transit Board carefully considers the feedback we receive through this formal comment process, and we'll respond to all substantive comments.  
  • After the Draft EIS public review and comment period, the Board will modify or confirm the "preferred alternative" for more study the Final EIS, in 2024. A preferred alternative is a statement of where the agency is leaning based on information available at the time. It's not a final decision.
  • The Board will make a final decision on routes and stations and the project to be built after we issue the Final EIS in 2024.
