Sound Transit changes service twice a year, in March and September. Each fall Sound Transit publishes an annual service plan for public feedback and Board approval. The resulting plan informs the next two service changes before the cycle starts again.

As our region responds to the COVID-19 pandemic, we are reducing Link, Sounder and some ST Express service beginning Monday, March 23 until further notice. This shift comes at the same time as our pre-scheduled Spring Service Change. Read below for pre-scheduled changes and see our Reduced Service page for COVID-19 related service reductions.

There are two categories of service changes, major and minor, that require different levels of approval and outreach before we can implement them. For more details, see the full 2019 Service Implementation Plan.

SERVICE CHANGES beginning March 2020

Changes begin March 21. Routes that do not have weekend service will change on Monday, March 23.

ST Express

  • North Eastside Mobility PlanSR 520 Changes
    • In partnership with King County Metro, Sound Transit has restructured bus service in the SR 520 corridor. The process also included extensive public collaboration and engagement with the cities of Redmond and Kirkland. After the King County Council approved changes to KCM service in July 2019, we were able to repurpose existing resources and implement new budget-neutral ST Express service between Redmond, Kirkland and South Lake Union. Impacted routes include: 540, 541, 542, and 544.
  • Route 540: Discontinue route; reinvest resources into new Route 544.
  • Route 541: Discontinue 33 trips due to low ridership and reinvest resources into new Route 544; retain nine trips. [NOTE: Route 541 is fully discontinued until further notice due to COVID-19 related service reductions.]
  • Routes 541 and 542: In westbound direction, both will switch from serving Bay 2 to new Bay 4 at University of Washington Station.
