Annual Service Plan
Recent and upcoming Link light rail openings mean there will be changes to existing ST Express bus service. Learn what these changes could look like for you.

North King and Snohomish counties

Currently, 1 Line trains run to Lynnwood City Center Station every 8 minutes during peak times and every 12-15 minutes late at night and early morning.  

When the full 2 Line opens with the start of service on the Crosslake Connection in early 2026, 2 Line trains will travel between Lynnwood City Center Station and Downtown Redmond Station.  

Combined 1 Line and 2 Line service between Lynnwood City Center and downtown Seattle will increase to every 4-5 minutes during the day.  

Additionally, the new Pinehurst Station is forecast to open in 2026, serving both the 1 Line and 2 Line. Pinehurst Station will be located on the west side of 5th Ave NE and 130th St and will serve a growing area between the existing Northgate and Shoreline South/148th stations. 

*Note: ST Express changes will not be implemented until Fall 2026.

Sound Transit currently provides ST Express service through seven routes to Everett, Seaway, Ash Way, Lynnwood, and Mountlake Terrace in north King County and Snohomish County through seven routes.

These ST Express routes serve about 6,000 riders daily; just under half take routes 512 and 535. Route 512 provides frequent service all day, all week between Everett and Lynnwood City Center, and Route 535 operates Monday – Saturday between Lynnwood and Bellevue. Routes 510, 513, 515, and 532 provide supplemental services during weekday peak hours.

  • 510 // Everett–Seattle
  • 512 // Everett–Lynnwood
  • 513 // Seaway–Lynnwood
  • 515 // Lynnwood–Seattle
  • 522 // Woodinville–Roosevelt
  • 532 // Everett–Bellevue
  • 535 // Lynnwood–Bellevue

When the 2 Line is fully open in 2025, both 1 Line and 2 Line trains will double the current Link service between Snohomish County and north King County. During peak times, trains will run every 4-6 minutes between Lynnwood and downtown Seattle. 2 Line riders can transfer to a 1 Line train at any station from Lynnwood City Center to International District/Chinatown.

From International District/Chinatown, 2 Line trains will head east from Seattle to Mercer Island, Bellevue, and Redmond via the Cross Lake Connection. 1 Line trains will continue south to SeaTac/Airport and Angle Lake. Riders can expect a trip from Lynnwood to downtown Seattle in 28 minutes and from Mountlake Terrace to Sea-Tac Airport in 56 minutes.

If you currently ride any of the bus routes listed above, your trip could look different when Link opens. Changes could include:

  • Buses that integrate with the growing Link light rail network.
  • Bus routes that have updated schedules.
  • More frequent and reliable service throughout the day – trains will arrive about every 8-10 minutes between 6 a.m. and 9 p.m.
  • More seats and overall capacity.
  • More connections to more places throughout the region.
  • A new option to avoid highway traffic.
