Tacoma Dome Link Extension

We want to hear from you on potential routes and stations

Publish Date
Body

The Tacoma Dome Link Extension (TDLE) will connect congestion-free regional light rail to south Federal Way, Fife, and Tacoma. Your input on the latest station and route options during this public comment of “scoping” period will help the Sound Transit Board determine which alternatives to study in the Draft Environmental Impact Statement (EIS). Over the past year, Sound Transit has worked with partner agencies, local stakeholders and the public to consider and further refine route and station alternatives.

The EIS documents TDLE’s potential impacts to the natural and built environment and will take about two years to complete, including the opportunity for public, agency, and Tribal comment following the Draft EIS. View our Determination of Significance (DS), which is a formal announcement to initiate scoping and preparation of an EIS and our Scoping Information Report, which provides an overview of the scoping process, the sites under consideration, and how to comment in further detail.

What is TDLE?

This project will extend the regional light rail system nearly 10 miles via mostly elevated tracks between Federal Way and Tacoma. This project includes four new light rail stations in areas near south Federal Way, Fife, east Tacoma, and the Tacoma Dome.

Stations will provide connections to other transit services in the region such as Sounder, Tacoma Link, Sound Transit Express, King County Metro, Pierce Transit, Intercity Transit and Amtrak.

Stations will feature pickup and drop-off zones and provide access for those travelling by foot, bike, paratransit and other modes.

The future South Federal Way and Fife stations each include approximately 500 parking spaces.
