Army Corps Plan to Work on Mississippi River Lock and Dam 25
USAgNet - 01/21/2022
A newly funded $732 million project is to complete the design and construction of a 1,200-foot by 110-foot lock chamber for Mississippi River Lock and Dam 25.
The project on the Upper Mississippi River near Winfield, MO, is part of a $22.81 billion plan to implement civil works studies, projects, and programs announced Wednesday (Jan. 19) by the U.S. Army Corps of Engineers (USACE).
The plan uses funding from the Infrastructure Investment and Jobs Act and the 2022 Disaster Relief Supplemental Appropriations Act.
Adjacent to the existing 600-foot by 110-foot lock chamber, the new chamber will enable a typical 15-barge tow — transporting more than 800,000 bushels of grain — to transit the lock in a single pass.
The new single-pass process (30-45 minutes) will vastly improve the current double-pass process (2+ hours), which requires breaking each barge tow into two sections.
This project is one of the seven authorized lock construction projects under USACE’s Navigation and Ecosystem Sustainability Program (NESP).
Lock and Dam 25 handles nearly all grain shipped on the Mississippi River from Illinois, Iowa, Minnesota, Missouri, and Wisconsin to export facilities near the Gulf of Mexico (on average, valued at over $3.6 billion annually over the past three years).
