Annual Service Plan
2027 Service Plan
Overview
Sound Transit’s Annual Service Plan sets priorities for upcoming service changes. Every year, Sound Transit service planners analyze routes based on ridership, performance trends, and other criteria to guide service modifications or additions.
The 2027 Service Plan proposals respond to changing ST Express ridership patterns, the expanding Link system’s need for more overnight maintenance time, and the future transition of some ST Express routes to Stride bus rapid transit.

2027 Service Plan Proposals
Below is information about service change proposals that, if approved by the Board of Directors, would be implemented in 2027.
ST Express
Routes 510 and 512
Everett – Seattle / Lynnwood
Due to low ridership and to simplify service, we propose ending service to these stops:
- Southbound early-morning Route 510 would no longer serve these stops in Everett:
- Hewitt Ave & Fulton St
- Hewitt Ave & Lombard Ave
- Wetmore Ave & Wall St
- Pacific Ave & Rockefeller Ave.
- Northbound late-night weekday Route 512 would no longer serve stops at:
- Pacific Ave & Rockefeller Ave
- Wetmore Ave & Wall St
- Hewitt Ave & Lombard Ave
- Hewitt Ave & Virginia Ave.
Routes 532 and 535
Everett/Lynnwood – Bellevue
Routes 532 and 535 are proposed to have a new stop at the new Stride station on I-405/NE 85th St in Kirkland. The station is expected to open in 2027.
The Stride S2 Line (Lynnwood – Bellevue) is expected to begin service in 2029.
Route 545
Redmond – Seattle
We propose to add a stop at Downtown Redmond Station to Route 545.
Route 560
Bellevue – West Seattle
Route 560 would no longer serve stops in West Seattle, ending at Burien Transit Center. In turn, frequency between Burien and Bellevue would increase as follows:
- Weekdays: Every 20 min (daytime), every 30 min (evenings)
- Weekends: Every 30 min all day (double current service)
For trips between Westwood Village and Burien, King County Metro's RapidRide H Line serves all current Route 560 stops in this segment. The H Line runs every 7-15 minutes on weekdays and every 15 minutes on weekends.
Burien Transit Center will also be the future western end of the Stride S1 Line, which will replace Route 560 as early as 2028.
Passengers looking to go from West Seattle to Seattle-Tacoma International Airport can take the H Line to connect to Route 560. Passengers can also take King County Metro Route 60 to connect to the 1 Line.
Link light rail
2 Line (Lynnwood – Redmond) and related Night Bus service changes
More time for routine maintenance = fewer disruptions
We know that unplanned disruptions on Link can greatly affect travel plans. One way to reduce unplanned disruptions is to allocate more time for planned routine maintenance on the Link system. This allows our crews to proactively address problems and resolve issues before they occur. In some areas of our system, we have limited time each night to perform this work, which constrains what crews can complete before service starts the next day.
No 1 Line changes are planned as part of our updated 2027 Service Plan proposal.
We propose ending 2 Line service earlier at night and starting service later in the morning. Night Bus Route 547 (Redmond – Seattle) would extend service to fill service gaps created by changes to the 2 Line schedule.
The proposed changes to 2 Line operating hours include:
Starting service approximately 25 minutes later in the morning, Monday through Sunday.
Ending service approximately 15 minutes earlier at night, Monday through Saturday.
Proposed changes to Link operating hours by day of the week
| Route | Hours of Service (Approximate) | Weekdays | Saturdays | Sundays |
|---|---|---|---|---|
| 2 Line | Current Service | 4 a.m. to 1 a.m. | 4 a.m. to 1 a.m. | 4:30 a.m. to Midnight |
| 2 Line | Proposed Service | 4:30 a.m. to 12:45 a.m. | 4:30 a.m. to 12:45 a.m. | 5 a.m. to Midnight |
(Rounded to nearest 15 minutes)
Proposed Route 547 service levels
| Route | Service Frequency (Minutes) | Weekday | Saturday | Sunday |
|---|---|---|---|---|
| Route 547 (Night Bus) | 30 | Midnight to 5:20 a.m. | Midnight to 6:20 a.m. | 11:30 p.m. to 5:20 a.m. |
If approved by the Sound Transit Board of Directors, service changes would be implemented in 2027. The implementation of these proposals is subject to operational capacity at our partner agencies and may be partially implemented or deferred.
*No major service changes are proposed for the following ST Express bus routes: 513, 522, 542, 556, 566, 574, 577, 578, 590, 592, 594, 595, and 596. If you have comments on these routes, or Sounder N Line or S Line, or T Line, please email servicechanges@soundtransit.org.
Enterprise Initiative
On May 28, 2026, the Sound Transit Board of Directors adopted an updated ST3 System Plan to guide the agency’s next phase of voter-approved transit expansion across the region as we work to close a $34.5 billion future funding gap. ST3 includes light rail extensions to West Seattle, Ballard, Tacoma, and Everett, new service between South Kirkland and Issaquah, and more. Learn about the Enterprise Initiative here.
The 2027 Service Plan proposals are consistent with the principles of the Enterprise Initiative to optimize resources and address financial and operational challenges in a transparent manner that is guided by rider input.
What’s Next
Your survey feedback will inform the development of our final service proposals this fall. We will present the final proposals to the Sound Transit Board of Directors in October for review. If approved, the final service proposals would be implemented in 2027.
