Construction update
The Locks and Dam 52 and 53 Replacement Project, known as the Olmsted Locks and Dam, is under construction between Illinois and Kentucky about 17 miles upstream from the confluence of the Ohio and Mississippi rivers. The locks are complete and work on the dam is 80 percent complete. Olmsted will replace locks and dams 53 and 52 and greatly reduce tow and barge delays through the busiest stretch of river in America's inland waterways. The Olmsted Locks and Dam are scheduled to be operational in 2018.
