Service changes for Sound Transit service will take effect starting Sept.17. The changes include additional reductions as well as extending reductions that were implemented at the end of 2021 on certain ST Express routes due to operator shortages. The reductions will affect frequency of service on weekdays.

In fall 2021, the Sound Transit Board of Directors approved service increases through the agency’s 2022 Service Plan. However, changing effects of the pandemic and broad employment trends have since resulted in nationwide transit operator shortages, requiring long-term trip cancellations and reductions on some ST Express routes, the agency said.

The service change dates are as follows:

• Saturday, Sept. 17, King County Metro-operated ST Express
• Sunday, Sept. 18, Community Transit-operated and Pierce Transit-operated ST Express
• Monday, September 19, Sounder
