Sound Transit announces overnight bus pilot service
January 15, 2026
Sound Transit announced today that a pilot overnight bus route between SeaTac and downtown Seattle will enter service on March 28. This new service will operate about every 30 minutes between 12 a.m. and 4 a.m.
“This overnight pilot will ensure 24- hour transit access from Seattle to the airport,” said Sound Transit CEO Dow Constantine. “While our proposed regional overnight bus network is still in development, adding this pilot now provides expanded flexibility for airport passengers and employees as we prepare to welcome the world during the FIFA World Cup.”
Buses will serve SeaTac/Airport and Tukwila International Boulevard before running express to downtown Seattle, serving stops near SODO, Stadium, International District / Chinatown, Pioneer Square, Symphony, and Westlake. Additional detail, including schedules and final stop locations, will be provided closer to the service launch date.
Riders can sign up to receive automatic email service alerts for Link light rail, ST Express bus routes, the T Line, and the Sounder N Line and S Line. Rider alerts provide information about schedule changes and help riders plan trips around inclement weather. Just go to Service alerts | Sound Transit
