The Upper Ohio Navigation Project is a multi-billion-dollar construction project that will replace locks at Emsworth, Dashields, and Montgomery locks and dams. The project will replace the auxiliary chambers, measuring 56 feet wide by 360 feet long, with locks measuring 110 feet wide by 600 feet long.
