Project background and next steps

The project will extend light rail south from Angle Lake in the City of SeaTac to the Federal Way Transit Center in 2024. By 2035, Federal Way Link will carry an estimated 35,000 to 39,500 riders each weekday through one of the most congested travel corridors in the region. Stations will be located in the Kent/Des Moines area, at South 272nd Street and the Federal Way Transit Center. The extension will provide a 46-minute trip between Federal Way and downtown Seattle regardless of traffic conditions.

The Sound Transit Board is expected to select the route and station locations at its Jan. 26 meeting. After securing a federal Record of Decision and completing the design work, the project is scheduled to enter construction in 2019.
