The Olmsted Locks and Dam is a locks and wicket dam on the Ohio River at river mile 964.4. The project is intended to reduce tow and barge delays by replacing the existing older, and frequently congested, locks and dams Number 52 and Number 53. The locks are located about 17 miles upstream from the confluence of the Ohio and Mississippi rivers at Olmsted, Illinois.
The Olmsted has been operational since August 2018 while the removal of Locks and Dams 52 and 53 was completed in 2023.[1][2] The project is both the largest and the most expensive inland waterway project ever undertaken in the United States.[3]
