*Aug. 18, 2022 update: Work is ongoing to identify new opening timelines for four light rail projects currently in construction. While the Federal Way Link Extension was planned to open near the end of 2024, we now expect construction completion to extend some number of months into 2025, depending on identified design solutions. An upcoming programmatic review will also assess shared resources and project sequencing. Expect further updates in Q4 2022.
