Open for bidding on Sound Transit's vendor portal in September 2026, closing 09:00 Pacific Time in September 2026. The portal record is marked Revised and Sound Transit states in the notice that the submittal and question due date will be updated intermittently to align with each submittal phase, so the date shown is the due date for the current phase and not the final proposal date; the Procurement Snapshot of August 2026 carries an estimated submittal date of March 2027 and a notice of intent to award or award of September 2027; participation deadline September 2026; no award recorded as of September 2026
