Sound Transit lands FTA Full Funding Agreement for light rail extension
The project will serve a dense suburban corridor where the existing roadway network is constrained and travel options are limited to two congested roadways.

The project is a 7.8-mile extension of the Link light rail system, from the existing Angle Lake station through the cities of SeaTac, Des Moines, Kent, and Federal Way in southern King County.

Federal Transit Administration (FTA) announced a $790 million Full Funding Grant Agreement (FFGA) with the Central Puget Sound Regional Transit Authority (Sound Transit) for the Federal Way Link Extension Project in King County, through FTA’s Capital Investment Grant (CIG) Program. Sound Transit has also been approved for up to $629.5 million in USDOT credit assistance through the Build America Bureau under the Transportation Infrastructure Finance and Innovation Act (TIFIA) program.
The project is a 7.8-mile extension of the Link light rail system, from the existing Angle Lake station through the cities of SeaTac, Des Moines, Kent, and Federal Way in southern King County. The project will serve a dense suburban corridor where the existing roadway network is constrained and travel options are limited to two congested roadways.
“Commuters in Seattle can now look forward to a one seat ride between King County, Sea-Tac Airport, downtown Seattle, and the University of Washington,” said FTA Acting Administrator K. Jane Williams. “This extension will improve access to jobs, healthcare, educational opportunities, and other destinations in the Puget Sound region.”
FTA’s CIG Program provides funding for major transit projects nationwide. Projects accepted into the program must go through a multi-year, multi-step process according to requirements in law to be eligible for consideration to receive program funds.
The Build America Bureau, which administers the TIFIA credit program, was established as a “one-stop shop” to streamline credit opportunities while also providing technical assistance and encouraging innovative best practices in project planning, financing, delivery, and operation.
