Sound Transit and the Federal Transit Administration plan to publish the draft environmental impact statement for the Ballard Link Extension on December 11, opening a public comment period through February 9, 2027. The review covers the full route from SODO to Market Street in Ballard.

Why it matters

The draft statement is a required step before Sound Transit can select a preferred alternative and move toward a final decision on the project. Only the SODO-to-Seattle Center segment is fully funded for construction, leaving the northern section dependent on a funding gap of an estimated $34.5 billion over the next two decades.

The proposed extension spans 7.7 miles, including a 3.3-mile rail-only tunnel, and the updated ST3 System Plan addresses an estimated $34.5 billion funding gap over the next two decades. The northern segment from Seattle Center to Market Street remains unfunded in the Long-Range Financial Plan.

The players

Sound Transit

Sound Transit is the regional transit agency that plans, builds and operates light rail, commuter rail and bus rapid transit across the Seattle metropolitan area.

Federal Transit Administration

The Federal Transit Administration is the U.S. Department of Transportation agency that provides financial and technical assistance for public transportation projects.

The details

The draft environmental impact statement covers the entire route to Market Street in Ballard, and the public can review the analysis and comment at virtual and in-person meetings or by email, voicemail, or mail. An online open house and printed copies will also be available during the 60-day comment period.

December 11, 2026: Draft environmental impact statement published and 60-day comment period begins.
February 9, 2027: Public comment period closes.
2027: Sound Transit Board confirms or modifies the preferred alternative.
2042: SODO-to-Seattle Center segment expected to open.

Roadmap

The draft environmental impact statement is prepared under the National Environmental Policy Act and the State Environmental Policy Act, the two frameworks that govern large federally and state-supported transit projects. Its release marks one stage in a sequence that will end with a final statement and a board decision on what is built.

Seattle residents who want to weigh in on the Ballard route can submit comments through virtual or in-person meetings, email, voicemail, or mail during the 60-day period. The SODO-to-Seattle Center segment is expected to open in 2042, so commuters in the corridor should expect changes to travel options over the coming years.

The takeaway

Residents who want influence over the Ballard route should use the public comment window that closes February 9, 2027. The northern segment's future depends on closing a large funding gap, so the next board decisions matter as much as the environmental findings.

What happens next

Sound Transit will publish the draft environmental impact statement on December 11, 2026, with public comments due February 9, 2027, followed by board confirmation of the preferred alternative in 2027.
