Colonel Andy J. Pannier assumed duties as the 55th Commander of the St. Louis District July 21, 2023 after serving as the deputy commander of the Mississippi Valley Division where he also served as secretary of the Mississippi River Commission.

The U.S. Army Corps of Engineers, St. Louis District will provide two opportunities for the public to tour the Motor Vessel MISSISSIPPI at no cost while it is in the region. Public open houses will take place: Saturday, August 5 from 1 – 4:30 p.m. along the riverfront in Cape Girardeau, Missouri. Tuesday, August 8 from 2 – 6 p.m. at the Melvin Price Locks and Dam in Alton, Illinois.

Lock and Dam 25 is located in Calhoun County, Illinois, and Lincoln County, Missouri, at approximately Mile 241.4 on the Upper Mississippi River above the mouth of the Ohio River near Winfield, Missouri. Proposed project features include construction of new 1200-foot, pile founded, lock located in the auxiliary miter gate bay, and construction of an upstream, ported guard wall totaling 1200 feet, and a 650-foot downstream approach wall. The existing 600-foot lock remains in place and will become auxiliary lock chamber to be used primarily by recreation traffic. The project also includes associated channel work, relocations and site-specific environmental mitigation. The majority of the Upper Mississippi River locks were designed and constructed in the 1930’s and the lock chambers are 600-ft. long. The 600-ft. lock chamber cause significant average delays to navigation because of double lockages required for tows larger than 600-ft.The new1200-foot lock will significantly reduce delays and increase safety. The combination of ecosystem and navigation in a single U.S. Army Corps of Engineers program required many years of coordination with both the navigation and ecosystem partners and it will alter the future of the Upper Mississippi River System to ensure it remains the vital transportation and ecosystem corridor for the next 100 plus years.

Engineers Far From Ordinary: The U.S. Army Corps of Engineers in St. Louis takes a look at the story of the St. Louis District beginning with the rich and legendary history of the river as well as the modern history of the District’s innovations in response to the challenges of simultaneously maintaining and regulating navigation, protecting again flooding, and protecting the environment.
