Project highlights


Link Light Rail


The Federal Way Link Extension project will extend light rail from the future Angle Lake Station at South 200th in SeaTac, which is under construction, to Kent/Des Moines by 2023. The project also develops a shovel-ready plan for extending light rail to the Federal Way Transit Center when additional funding is secured. The corridor is about 7.6 miles long and parallels SR 99 and Interstate 5.
