Sound Transit Overhauls ST3, Delays Projects Over $34.5 Billion Funding Gap
4 articles · Updated · KING5.com · May 30
Sound Transit’s board approved a revised ST3 expansion plan after concluding the 2016 voter-approved schedule can no longer be financed under current projections.
$34.5 billion in projected shortfalls stems from higher construction and operating costs, inflation and weaker-than-expected revenue, with the biggest strain emerging in the mid-2030s.
West Seattle Link remains funded but loses Avalon Station, while Ballard Link is fully funded only to Seattle Center; the Seattle Center-to-Market Street segment lacks construction funding.
By Aug. 1, 2026, the agency must publish a fixed date or date range for service to Smith Cove, Interbay and Ballard after riders and advocates pressed for clearer commitments.
Sound Transit said deferred pieces could still advance later if new revenue, cost savings or other funding sources materialize, preserving the broader ST3 vision.

Can new taxes and fare gates truly fix a $34.5 billion funding gap to deliver the transit system Seattle was promised?
