Sound Transit is warning passengers of a series of late-night Link light rail disruptions across Seattle, Bellevue and Redmond during September, as crews carry out maintenance and upgrade work.
The changes will affect the 1 Line and 2 Line on selected nights, with buses replacing trains on some sections. Other services will continue, but passengers may need to board from a different platform or allow extra time for their journey.
Link light rail disruptions in September
From September 1 to 3, and again on September 10, shuttle buses will replace 2 Line trains between South Bellevue and Overlake Village from 11pm until the end of service. The work will allow crews to replace surge arrestors.
Shuttle buses are expected to run every 10 to 15 minutes. Trains will continue between Downtown Redmond and Overlake Village, and between South Bellevue and Lynnwood City Centre.
A further interruption is planned from September 15 to 17, when buses will replace both 1 Line and 2 Line trains during late-night hours between SODO, Judkins Park and Capitol Hill for scheduled monthly maintenance.
During that work, 1 Line services will run in two separate sections: between Lynnwood and Capitol Hill, and between SODO and Federal Way. The 2 Line will operate between Judkins Park and Downtown Redmond.
From September 21 to 25, and September 28 to 30, 2 Line trains will share a single track between Mercer Island and South Bellevue while fencing is installed along the route.
Sound Transit says there will be no timetable changes for the 1 Line or 2 Line during this work. However, passengers using Mercer Island station will board trains travelling in both directions from the same platform.
Another single-track operation is scheduled between South Bellevue and Downtown Redmond from September 24 to 28 while crews carry out rail milling.
The process mechanically removes defects and reshapes the rail profile, helping to extend the life of the tracks and provide a smoother ride. No scheduled service changes are expected as a result.
Sound Transit said the planned reductions were necessary to maintain and improve the Link network. Passengers have been advised to check the agency’s service alerts before travelling.
