What is the Everett Link Extension? The Everett Link Extension is a planned 16-mile light rail line connecting Snohomish County communities — including Lynnwood, Mariner, Paine Field, and Everett Station — to the regional Sound Transit light rail network. It was included in the ST3 ballot measure approved by Puget Sound voters in 2016, with an original 2021 cost estimate of $6.6 billion.
On the evening of April 14, a standing-room-only crowd packed Everett Station to hear Sound Transit explain what is happening with the light rail extension their communities voted for — and to press officials on whether it will be built on anything close to the original terms.
The short answer: Sound Transit faces costs that have climbed between $200 million and $1.1 billion above the original 2021 estimate for the Everett extension alone, as part of a system-wide budget challenge the agency describes as a $34.5 billion gap. The timeline has already slipped. And one of the scenarios the agency is weighing would not complete the connection to Everett at all.
Why Costs Have Climbed
Sound Transit attributes the cost increases to a combination of forces that have hit infrastructure projects broadly in recent years: inflation, tariffs on construction materials, labor shortages, supply chain disruptions, and escalating right-of-way acquisition costs. Together, these factors have driven costs up 20 to 25 percent above what the agency’s 2021 financial plan assumed.
For the Everett Link Extension specifically, the increase ranges from $200 million on the low end to $1.1 billion on the high end — on top of the original $6.6 billion estimate. That would put the project’s total cost at up to approximately $7.7 billion, depending on which scenario the Sound Transit Board pursues.
The Timeline Has Already Slipped — Significantly
When Snohomish County voters approved ST3 in 2016, the Everett Link Extension was projected to open in 2036. That target has already moved. Sound Transit now says the first phase — reaching as far north as Paine Field — may open by 2037, with the full extension to Everett Station potentially not arriving until somewhere between 2037 and 2041.
A five-year window of uncertainty for a project’s completion date is itself a signal of how unsettled this extension’s future is. For residents who counted on light rail as a long-term alternative to the I-5 and Highway 2 commute into King County, that uncertainty is not abstract.
Three Scenarios — Including One That Stops Short of Everett
The most consequential piece of information for Everett residents at Tuesday’s town hall: Sound Transit is weighing three different approaches to closing its budget gap, and at least one of those scenarios would not complete the connection to Everett Station.
The agency has not publicly labeled all three options by name, but previous Sound Transit documents have described approaches ranging from phasing the extension to terminate before reaching downtown Everett, to pursuing new financing mechanisms, to restructuring which ST3 projects get built first and on what timeline.
For a city that anchored a significant portion of its long-term transit vision around being the northern terminus of Puget Sound light rail, the prospect of a scenario that bypasses Everett Station drew pointed and sustained questions from the crowd.
Mayor Franklin and County Executive Somers Were in the Room
Snohomish County Executive Dave Somers and Everett Mayor Cassie Franklin attended the April 14 town hall and were available to take questions alongside Sound Transit staff. Both officials have consistently advocated for the full Everett extension as a critical piece of the region’s transportation and economic development future.
The day before the town hall, the Everett Herald’s editorial board published a call for Sound Transit to “exhaust every option to keep light rail on track” — a signal of the urgency local leaders and media are placing on this decision.
What Happens Next
Sound Transit’s board is expected to evaluate updated approaches to the ST3 System Plan in summer 2026. That decision will determine whether the Everett Link Extension proceeds on a modified but still-complete schedule, gets phased to stop short of Everett Station, or faces some other restructuring.
Residents who want to weigh in before that decision can:
- Attend Sound Transit Board meetings, which are open to public comment
- Submit written comments through soundtransit.org
- Contact Snohomish County’s elected Sound Transit Board representatives directly
- Reach out to Mayor Franklin’s office or the Snohomish County Executive’s office
What This Means for Everyday Commuters
Light rail was a central promise of the ST3 campaign: a reliable, car-free connection linking Everett to Seattle and the broader regional network. Lynnwood Link opened in 2024, giving riders a northern terminus — with buses bridging the gap into Snohomish County. That arrangement was always intended to be temporary, until the Everett extension was complete.
If the extension is scaled back or further delayed, Everett-area commuters would remain dependent on transfers and bus connections for years — or decades — beyond what voters were told in 2016. For a region that has some of the country’s most congested commutes, the stakes of this summer’s board decision are substantial.
Frequently Asked Questions About the Everett Link Extension
When will the Everett Link Extension open?
Sound Transit currently projects the first phase to Paine Field opening by 2037, with the full extension to Everett Station arriving between 2037 and 2041. Both timelines are subject to further change pending the board’s summer 2026 decisions.
How much will the Everett Link Extension cost?
The original 2021 estimate was $6.6 billion. Costs have increased between $200 million and $1.1 billion above that figure, meaning the project could cost as much as approximately $7.7 billion depending on the scenario Sound Transit pursues.
Could the light rail extension stop short of Everett?
Yes, this is one of at least three scenarios Sound Transit is considering to address its $34.5 billion system-wide budget gap. No final decision has been made — the board is expected to act in summer 2026.
When will Sound Transit decide on the Everett extension’s future?
The Sound Transit Board is expected to take up ST3 System Plan updates in summer 2026.
Who attended the April 14 Everett transit town hall?
Snohomish County Executive Dave Somers, Everett Mayor Cassie Franklin, and Sound Transit representatives attended and took questions from a standing-room-only crowd at Everett Station.
What is ST3?
ST3 is the third Sound Transit ballot measure, approved by voters in the greater Puget Sound region in November 2016. It authorized funding for multiple light rail expansions, including the Everett Link Extension connecting Snohomish County to the regional network.
How can Everett residents give input on the Everett Link Extension?
Residents can attend Sound Transit Board meetings, submit comments at soundtransit.org, or contact their elected Sound Transit Board representatives and local officials including Mayor Franklin’s office or Snohomish County Executive Dave Somers’ office.
