The recommended plan identifies a new shallow-draft lock chamber 900 feet long by 110 feet wide, sited roughly 2,400 feet north of the existing lock, and the existing lock would continue operating during construction. A 30-day public review runs through August 10, 2026; the final report incorporates changes from a 2025 draft review, including an updated Community Impact Mitigation Plan for the surrounding neighborhoods. Advancement beyond this phase depends on congressional authorization and funding.
