About Route 535

Route 535 was one of Sound Transit's original nine ST Express regional bus routes that began service on September 19th, 1999. The 535 is operated under a contract with Community Transit. As part of Sound Transit's fall 2026 service change plan, route 535 could soon be improved to having 30 minute frequencies on weekends with 60 minute frequencies in evening hours. This plan would also introduce Sunday service to the 535 for the first time.

Route 535 operates between Downtown Bellevue and Lynnwood City Center Station. The route operates between 4:40am and 11:10pm on weekdays with 30 minutes frequencies most of the day, 60 minute frequencies in the evening and late-night hours. On Saturdays, the route opperates between 7am and 10pm with 60 minute frequencies all day. The route does not operate on Sundays.

Major destinations and points of interest along the route include Downtown Bellevue, Bellevue Transit Center, Totem Lake Freeway Station, Brickyard Freeway Station, Downtown Bothell, UW Bothell, Canyon Park Freeway Station, Alderwood Mall, and Lynnwood City Center Station.
