Factsheet: Upper Ohio Navigation Project, Pennsylvania
Location: The project is located at Emsworth (Ohio River Mile 6.2), Dashields (Ohio River Mile 13.3), and Montgomery (Ohio River Mile 31.7) Locks and Dams, along the Upper Ohio River near Pittsburgh, PA.
Purpose: The authorized project’s purpose is to provide safe, reliable, and efficient navigation through some of the oldest locks on the Ohio River by replacing each auxiliary 56’ x 360’ lock at Emsworth, Dashields, and Montgomery with a new 110’ x 600’ lock to serve as the new main lock chamber.
Project Description and Background: The Upper Ohio River Navigation Project addresses lock condition and capacity issues at Emsworth, Dashields, and Montgomery Locks and Dams on the Ohio River in Pennsylvania. All three facilities were constructed between 1919 and 1936, and each underwent a major rehabilitation in the 1980s to extend their useful life another 25 years. The Chief’s Report recommends replacement of each auxiliary lock with construction of one new lock chamber (110’ wide by 600’ long) at each facility riverward of the existing main lock chamber. This new lock chamber would serve as the main lock chamber. The Chief’s Report was signed on September 12, 2016, and the project was authorized in the 2016 Water Infrastructure Improvements for the Nation Act.
