Q: Will Sound Transit build light rail to Everett Station?
A: That decision hasn’t been made yet. The Sound Transit Board will vote on a restructured ST3 System Plan in summer 2026. At least one scenario under consideration would not complete the extension to downtown Everett Station. The first phase to Paine Field may open by 2037; the full connection to Everett Station could arrive between 2037 and 2041 — or not at all under a phased scenario.

Sound Transit’s Everett Link Extension: The Complete 2026 Guide to Light Rail’s Uncertain Future

In April 2026, the future of light rail in Everett is genuinely uncertain in a way it has never been before. Costs for the Everett Link Extension have climbed between $200 million and $1.1 billion above the 2021 estimate. Sound Transit is weighing scenarios that could defer or eliminate the connection to Everett Station entirely. And the Sound Transit Board will make its defining decision on the ST3 System Plan this summer.

This is the complete guide to where the Everett Link Extension stands, why it matters, what the scenarios are, and what you can do before summer 2026.

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 approved as part of the ST3 ballot measure by Puget Sound voters in November 2016, with an original 2021 cost estimate of $6.6 billion.

The extension would add six stations north of the existing Lynnwood Link terminus: West Alderwood, Ash Way, Mariner, SW Everett Industrial Center (serving the Paine Field corridor), SR 526/Evergreen, and Everett Station at the heart of downtown. Those six stations represent a fundamental change in how Everett connects to the region — a car-free, congestion-proof link from Paine Field to Seattle’s core.

The Cost Problem: $200M to $1.1B Above Estimates

Sound Transit attributes the cost escalation to factors that have hammered infrastructure projects across the country: inflation running above projections, tariffs on construction materials, labor shortages in the skilled trades, supply chain disruptions, and rapidly escalating right-of-way acquisition costs. Together, these have driven costs 20 to 25 percent above the 2021 Financial Plan baseline.

For the Everett extension specifically, that means a range of $200 million to $1.1 billion in added cost — on top of the original $6.6 billion. The project could cost as much as $7.7 billion. Set against Sound Transit’s described $34.5 billion system-wide budget gap, the Everett extension is one of the agency’s most expensive unresolved commitments.

The Timeline Has Already Slipped — And Could Slip Further

When Snohomish County voters approved ST3 in November 2016, the Everett Link Extension was projected to open in 2036. That date has already moved. Sound Transit’s current projections put the first phase — reaching Paine Field — as early as 2037. The full extension to Everett Station carries an estimated opening window of 2037 to 2041.

A five-year uncertainty window for a single project’s completion date signals how unresolved this extension’s future actually is. For Everett residents who incorporated light rail into their long-term housing, employment, and transportation decisions, the uncertainty is not abstract.

The Three Scenarios — Including One That Stops Short

The most consequential revelation from April 14’s standing-room-only town hall at Everett Station: Sound Transit is evaluating at least three approaches to its budget challenge, and at least one scenario would not complete the connection to Everett Station downtown.

Sound Transit’s Board has been considering approaches ranging from restructuring the phasing of ST3 projects — with some extensions potentially terminating before their original endpoints — to pursuing new financing mechanisms and federal funding sources. Previous Sound Transit documents describe options that could have the Everett extension terminate before reaching downtown Everett Station, leaving the corridor without its planned terminus for years beyond what voters expected.

For a city that anchored its long-term transit planning around being the northern terminus of Puget Sound light rail, this scenario drew sustained and pointed questions from the standing-room crowd at Everett Station on April 14.

Who Was in the Room — and What They Said

Snohomish County Executive Dave Somers and Everett Mayor Cassie Franklin attended the April 14 town hall in person, taking questions alongside Sound Transit staff. Both officials have been consistent advocates for the full extension to Everett Station as a pillar of the region’s transportation and economic development future.

The day before the town hall, the Everett Herald’s editorial board published a direct call for Sound Transit to “exhaust every option to keep light rail on track” — a signal of the urgency local elected officials and media are placing on this summer’s decision. Snohomish County’s elected Sound Transit Board representatives have similarly advocated against any scenario that defers or eliminates the Everett Station terminus.

Why the Paine Field Station Is Especially High-Stakes

The SW Everett Industrial Center station — commonly called the Paine Field station — is one of the most consequential stops in the entire ST3 project list. Paine Field is home to Boeing’s widebody assembly operations, the largest factory building by volume on earth. It’s also home to Paine Field International Airport (PAE), Snohomish County Airport, and over 600 aerospace suppliers that make up the $14 billion Snohomish County aerospace economy.

A light rail connection to Paine Field would be transformative for the 30,000-plus workers commuting to the corridor daily — reducing parking pressure, cutting commute times from Seattle and south King County, and connecting the aerospace workforce to regional transit. If the Paine Field station is preserved but the Everett Station connection is deferred, Boeing and aerospace workers would gain access while Everett’s downtown remains disconnected.

What Happens Next — The Summer 2026 Decision

The Sound Transit Board is expected to take up ST3 System Plan restructuring in summer 2026. That vote 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 another restructuring.

Between now and then, Sound Transit will continue accepting public comment. The April 14 town hall was one of multiple public engagement events the agency is holding across the ST3 service area.
