As part of its 2026 Service Plan, Sound Transit is proposing a new overnight bus service in the corridor of the Link 1 and 2 Lines. These routes would also continue to Everett, Tacoma, and Lakewood. These services will specifically operate during the night after Link stops running, and end shortly before Link begins again the next morning. Service is scheduled to launch in the fall of this year, contingent on the ability of partner agencies to deliver the service. Sound Transit is also launching a pilot of this service on the segment from downtown Seattle to SeaTac starting March 28th, with service roughly every 30 minutes throughout the night.
Despite shadowing the Link 1 Line, the overnight service proposal skips 10 out of 26 current 1 Line stations. Intuitively, the reason for skipping so many stops is probably is to keep the bus moving quickly as it heads to Everett or Lakewood, as well as to keep operating costs and staffing levels manageable. Also, considering that Sound Transit is a regional agency rather than a local one, they may be leaning on King County Metro to provide night-owl service within the city of Seattle. However, though some of the gaps are covered by King County Metro’s own night-owl network, there is not as much overnight service along parts of the 1 Line as you might think.
