Construction began on Olmsted Locks and Dam in 1996 and continues today. Locks and dams Nos. 52 and 53 will be replaced with this single facility at mile 964.4 of the Ohio River in Ohio. The Olmsted project involves underwater foundation preparation, lift-in constructionof the tainter gates and navigable pass shells for the dam, floating approach walls, directly connected hydraulic cylinder operation of the culvert valves, miter gates, tainter gates and a central station to operate both the dam and the twin locks. The project currently is scheduled for a 2021 completion, depending upon funding. This project is unique in the fact that it's the first precast spillway the Army Corps of Engineers has constructed. The project has entered its final phase of constructing the dam extending across the Ohio River.
