Three U.S. Army Corps of Engineers Pittsburgh District contractors watch a crane remove asphalt from the parking lot at Montgomery Locks and Dam in Monaca, Pennsylvania, May 29, 2025. The pictured section of the parking lot will be used as a foundation for a temporary utility bridge as well as for concrete conveyors to transport concrete from the on-site batch plant to the lock chamber throughout construction. Building the batch plant will allow contractors to produce 400,000 cubic yards of concrete on-site for a new navigation chamber at Montgomery Locks and Dam.
The Upper Ohio Navigation Project is part of the National Economic Development (NED) plan for improving the upper Ohio River navigation system, specifically the Emsworth, Dashields and Montgomery locks and dams. Emsworth, Dashields and Montgomery, each constructed prior to 1936, are the first three locks and dams on the Ohio River downstream of the Point of Pittsburgh. The three facilities have the oldest and smallest lock chambers operating along the entire river.
The project involves replacing the auxiliary chamber at Montgomery Locks and Dam, measuring 56 feet wide by 360 feet long, with locks measuring 110 feet wide by 600 feet long. The Pittsburgh District expects the project to support more than 15,000 jobs nationally throughout the construction period.
Transporting commodities on the waterways is four times less expensive than by truck and 33 percent cheaper than by rail. Between 15 million and 20 million tons of cargo travel on the upper Ohio River each year, including mainly coal, but also coke, petroleum products, raw and finished steel, and aggregates.
