West Seattle Link Light Rail Extension Service Delayed to 2035
Sound Transit has announced that the West Seattle Link light rail extension will now begin service in 2035, a change from previous timelines after an agency review.

Seattle Tacoma, WA, August 14, 2026 —
Sound Transit has announced a revised service start date for the West Seattle Link light rail extension, now slated for 2035. This adjustment marks a shift from earlier projected timelines, following a comprehensive agency review.
The decision to push back the opening date was made after the agency conducted an internal review of the project’s progress and planning. Specific details regarding the reasons for the revised timeline beyond the general agency review were not immediately available.
The West Seattle Link extension is a significant transit project aimed at expanding light rail service to the West Seattle area. Previously, the project had different target dates for its completion and the commencement of passenger service. The new 2035 date is now the official target for the extension to become operational.
Further updates or detailed explanations for the timeline revision are expected from Sound Transit as the project progresses. The agency has not provided information on potential impacts to other related projects or procurements stemming from this schedule change.
