In November 2008, voters approved funding for the segment between Sea-Tac Airport and Redondo/Star Lake at South 272nd Street. However, reduced tax revenue as a result of the economic recession led Sound Transit to suspend all work south of Angle Lake Station in December 2010. Construction on the South 200th Link Extension to Angle Lake station began in April 2013. Angle Lake station opened to the public on September 24, 2016. On July 23, 2015, the Sound Transit Board selected their preferred alternative for the Federal Way Link Extension, routed along the west side of Interstate 5 with three stations serving Highline College, the Star Lakepark and ride and Federal Way Transit Center. Funding for preliminary engineering on the southern segment was restored in February 2016, allowing for planning to resume. The Sound Transit 3 ballot measure was passed by voters in 2016, including funding and approval to open Federal Way Link in 2024, from Angle Lake to Federal Way Transit Center via Star Lake and Kent/Des Moines. The final alignment for the line was chosen in January 2017, with an agreement signed with Federal Way Public Schools to move an elementary school near South 272nd Street station. In July 2018, the project's estimated cost was revised to $2.55 billion, due to land acquisition costs and limited availability of suitable contractors. The Federal Transit Administration awarded a $790 million grant and $629 million loan to Sound Transit for the project in December 2019. Construction began in early 2020, which was commemorated with a virtual groundbreaking ceremony due to the COVID-19 pandemic. Light rail service to Federal Way is planed to open in late 2024.
Route
From Angle Lake station, the terminus of the South 200th Link Extension, the line will travel southeast along the planned State Route 509 freeway extension to Interstate 5. From there, trains will run on the west side of I-5, serving Highline College at Kent/Des Moines station, and a park-and-ride at South 272nd Street near Star Lake, before ending at the Federal Way Transit Center. A new operations and maintenance facility will be constructed near Kent/Des Moines station or south Federal Way to support operations of the future Tacoma Dome Link Extension. The proposed Kent/Des Moines site is at the former Midway Landfill, replacing an earlier proposal that was withdrawn after public concerns over the displacement of a Dick's Drive-In.
