This morning, Sound Transit announced the official opening day of the Federal Way Link Extension, which will extend the 1 Line to three new stations beyond its current terminus at Angle Lake. An opening ceremony will be held across the extension on Saturday, December 6, 2025, kicking off full 1 Line service to the new terminus at Federal Way Downtown.
When it broke ground in 2020, the extension was expected to open in 2024. Completion was eventually delayed to mid-2026 following due to impacts from the 2020 pandemic, a 140-day concrete truck driver strike (KUOW), and the discovery of unstable soils next to I-5 south of the Midway Landfill (Sound Transit).
However, construction appears to have proceeded ahead of schedule. Earlier this summer, Sound Transit CEO Dow Constantine announced the agency would be making every effort to open the extension as soon as possible, even if it meant usurping the cross-lake connection of the 2 Line between Bellevue and Seattle as the next major expansion of the Link system. Opening of the cross-lake connection is now tracking toward next spring.
