Upcoming planned closures on the 1 Line starting November 8, 2025

Sound Transit initiates planned 1 Line service suspensions starting November 8 to support repairs, maintenance, and necessary integration of the 2 Line. The first disruption will occur between U District and Westlake, with bus replacements provided for affected passengers. Following this, service will halt between Capitol Hill and Stadium to address a cracked rail, alongside further early closures to extend overnight maintenance. The work is scheduled to persist through January 2026, with future dates to be determined. Sound Transit encourages riders to sign up for email alerts to receive timely updates on service changes and rider alerts.

These measures are designed to improve the overall safety and reliability of transit services in the region. The integration of advanced signaling in the Downtown Seattle Transit Tunnel is a key aspect of the upcoming work. Passengers should prepare for delays and plan accordingly during these service interruptions.
