North Subarea – Lynnwood Link Extension & Bus Service Restructure

Thank you for your interest in the 2024 Service Plan. The feedback period for this online open house was from July 10 to Aug. 6, 2023 and is now closed. For more information about the 2024 Service Plan please visit our website.

Ahead of light rail extending to Lynnwood as early as summer/fall 2024, this 2024 Service Plan is proposing changes to light rail and express bus service. We invite you to learn about the proposed changes in the north subarea and share your feedback with us.

Information on the east and south subareas is available on the 2024 Service Plan website.

A map showing proposed changes to Sound Transit's services in the north subarea, which connects Snohomish County and North King County to the Seattle area. The map shows the proposed changes in the context of the areas north and east of Seattle.

The map shows a Sounder train route from Everett to King Street Station. Link light rail lines (referred to as the 1 Line on the map) are also shown. The 1 Line is depicted in green showing the route once Lynnwood Link Extension opens; Lynnwood City Center is shown in the north and Mt. Baker in the south. The 2 Line is also shown, but with a different shading depicting the East Link Starter Line from South Bellevue to Redmond Technology. The remainder of the 2 Line that could potentially open later than the East Link Starter Line is shown with a lighter coloring; those areas that may open later stretch from downtown Seattle to South Bellevue, as well as the area between Redmond Technology and Downtown Redmond. 

The map also shows proposed changes to Express bus routes. Route 522 is shown running from Woodinville to Roosevelt Station in Seattle, route 512 is shown from Everett to Lynnwood City Center and 513 is shown from Seaway Transit Center to Lynnwood City Center. Routes 510 and 511 are depicted in a light gray dotted line, indicating that Sound Transit is proposing eliminating routes 510 and 511 in 2024 — Proposed changes to all of Sound Transit’s north subarea routes are shown in the above map | Click to enlarge

1 Line Extension to Lynnwood

As early as summer/fall 2024, Link light rail will extend from Northgate into Snohomish County, serving four new stations: Shoreline South/148th, Shoreline North/185th, Mountlake Terrace, and Lynnwood City Center. An additional station will open at NE 130th Street in 2026.

Service to Lynnwood was originally planned to open as an extension of both the 1 Line (Lynnwood–Angle Lake) and the 2 Line (Lynnwood–Redmond). However due to construction delays on the I-90 bridge delaying full 2 Line service into 2025, service to Lynnwood will initially operate as an extension of the 1 Line only, with trains up to every eight minutes during peak hours, every 10 minutes midday, evenings and weekends, and every 15 minutes early morning and late at night.

We’re continuing to evaluate how often trains will run when the four new stations open next year. We anticipate trains will be crowded at times due to fewer trains running than we planned, and we are working hard to provide the most service possible within our constraints.

You can stay up to date on construction progress and service opening dates for this and other Sound Transit projects here.

What you should know:

The 1 Line is extending from Northgate to Lynnwood and will open as early as summer/fall 2024. Trains could run every eight minutes during weekday peak hours.
Service to Lynnwood will roughly double when the full 2 Line opens in 2025.
Visit the project website for more details about the four new stations.
Our partner agencies will change bus service to connect to Link trains as well. Visit King County Metro’s Lynnwood Link Connections website and Community Transit’s Transit Changes page for more details.

Timelines are subject to change

These proposals are not final and may change, be partially implemented or deferred in response to partner agency operating capacity.

The Link light rail route is described as the 1 Line, which will be the route line name once other Link extension lines open in the future. The 1 Line route is depicted in green on the map, as it stretches from Lynnwood City Center in the north to Northgate Station in the south. Future stations are shown along the 1 Line with a circle, along with the station names. The future stations, from the northernmost station to the southernmost station shown in the map, are as follows: Lynnwood City Center, Mountlake Terrace, Shoreline North / 185th, Shoreline South / 148th, Northeast 130th, and Northgate Station. Please note the Northeast 130th Station is anticipated to open at a later date in 2026.

The map also depicts the future 2 Line, which will stretch from Lynnwood City Center to Redmond once fully open. The 2 Line is illustrated with a light blue dotted line. The full 2 Line potential opening timeframe is spring 2025. — Link light rail service will extend from Northgate to Snohomish County as early as summer/fall 2024 | Click to enlarge

ST Express changes

When 1 Line trains extend to Lynnwood, Sound Transit is proposing changes to ST Express bus service in the area to connect riders with new Link stations. New 1 Line service offers a reliable alternative to I-5 congestion and provides an opportunity to change bus service to run more often and/or seven days a week. For example, existing bus routes that currently end at Northgate Station could end at Lynnwood City Center instead, and those service hours can be reinvested to provide more bus service with the same resources.

To see how your Express bus route may change, see the proposed changes below.

510 (Everett – Seattle)

To improve reliability along the congestion of I-5 and to provide all-day, all-week connections, we are proposing to eliminate Route 510 and replace it with additional service on Route 512.
Route 512 would also be shortened to run from Everett Station to Lynnwood City Center Station, operating all-day, two-way service seven days a week. Passengers continuing to Mountlake Terrace, Shoreline or Seattle would connect to 1 Line trains at Lynnwood City Center Station.
The three early morning trips that serve stops north of Everett Station prior to 5 a.m. will not be replaced by Route 512 service. See the Route 512 section for the reasons behind this change.

511 (Ash Way – Northgate)

Due to ongoing operator staffing shortages, in March 2023, Route 511 was suspended. Riders can use service on Routes 512 and 513.
Route 511 will not be reinstated. When the 1 Line trains extend to Lynnwood, riders can access service on Routes 512 and 513 and the 1 Line.

The map shows Express route 511 in a light gray dotted line compared to the more strongly colored routes depicting Sounder train service, Link light rail service and other Express bus routes.

Express route 511 is depicted in light gray (as it is currently suspended), as it ran between south Everett and Northgate. The proposed route change will formally eliminate Express route 511 once Lynnwood Link Extension opens since the service area will be serviced by other Sound Transit services such as Link light rail and other Express bus routes. Route 512 will replace 511's service area to give the area more frequent service, including weekends. — Proposed changes to the ST Express Route 511 in the area between Ash Way and Northgate | Click to enlarge

512 (Everett – Northgate)

Route 512 will be shortened to run from Everett Station to Lynnwood City Center Station, operating all-day, two-way service seven days a week. Passengers continuing to Mountlake Terrace, Shoreline or Seattle would connect to 1 Line trains at Lynnwood City Center Station. Moving the connection north to Lynnwood allows passengers to spend less time in traffic and provides the same access as today, but is more reliable due to less time spent on I-5.
Service would double during peak hours, with buses every eight minutes, and increase by 50% midday, with buses every 10 minutes.
Sound Transit proposes to eliminate the early morning/late evening stops north of Everett Station due to very low ridership and in order to facilitate possible new early morning/late evening service continuing south of Everett Station at a future date. Eliminating these stops allows for more frequent Route 512 service between Everett Station and Lynnwood City Center. The proposed eliminated stops are:
- Pacific Avenue & Rockefeller Avenue
- Wetmore Avenue & Wall Street
- Hewitt Avenue & Lombard Avenue
- Hewitt Avenue & Virginia Avenue

The map shows Express route 512 in a strong dark blue line compared to other colored routes depicting Sounder train service, Link light rail service and other Express bus routes. Both the existing route 512 service area, as well as the future route 512 service area, are illustrated - the future route is bolded while the existing route is shown in a light gray dotted line.

The current Express route 512 in light gray is depicted as it currently runs from Everett to Northgate Station along Interstate 5. However, the future route in dark blue is depicted running from Everett in the north, to the new southernmost destination at Lynnwood City Center, which will be the southernmost destination once Lynnwood Link Extension opens. — Proposed changes to the ST Express Route 512 in the area between Everett and Northgate | Click to expand

513 (Seaway Transit Center – Northgate)

ST Express Route 513 will be shortened to operate between Seaway Transit Center and Lynnwood City Center Station.
Moving the connection north to Lynnwood allows our riders to spend less time in traffic and provides the same access as today, but is more reliable due to less time spent on I-5.
Route 513 will add service, now operating every 15 minutes in both directions, during peak hours.

522 (Woodinville – Roosevelt)

Route 522 currently connects to the 1 Line at Roosevelt Station.
There are no proposed changes to ST Express Route 522 in 2024. We are recommending that changes to Route 522 wait until the full 2 Line is open in 2025. When the full 2 Line extends to Lynnwood, Route 522 will be shortened to connect to the 1 and 2 Lines at Shoreline South/148th Station. Moving the connection north to Shoreline South/148th Station is consistent with future Stride S3 Line service.
We'll continue to work closely with King County Metro to plan local service for stops south of 145th Street through the Lynnwood Link Connections project.

Route 522 will be replaced in a few years by Sound Transit’s new Stride S3 Line. The Stride S3 opening date is still under review.

Express route 522 in dark blue is depicted as it currently runs from Woodinville to Roosevelt Station along Highway 522. There is no proposed change to Express route 522 service in 2024. However, this route will eventually be replaced by the Stride Bus Rapid Transit service. — Proposed ST Express Route 522 service in 2024 in the area between Woodinville and Roosevelt | Click to expand
