  • Emsworth Locks & Dams Major Rehabilitation Project

    Emsworth Locks and Dams are located on the Ohio River immediately downstream of the City of Pittsburgh. The main channel dam and locks are located at river mile 6.2 and the back channel dam is located at river mile 6.8. The project creates the navigation pool for the City of Pittsburgh. The structural components of the Emsworth Locks and Dams are the oldest of any project on the Ohio River, dating back to 1919 to 1922 and 1935 to 1938 when Emsworth Dams were constructed. The Emsworth locks, consisting of a 110’ wide by 600’ long main chamber and 56’ wide by 360’ long auxiliary chamber, are the oldest on the Ohio River System and are in need of additional maintenance work to keep them operating safely until permanent improvements are implemented.
  • Upper Ohio River Navigation Project

    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. These facilities have the oldest and smallest lock chambers in the entire Ohio River Navigation System. The project replaces each auxiliary lock chamber (56’ wide by 360’ long) with a new lock chamber (110’ by 600’) at each facility. This new lock chamber would serve as the new main lock chamber. The fully-funded, total project cost for all three new chambers is $2.1 billion, which would be cost-shared jointly by the General Fund (65%) and the Inland Waterways Trust Fund (35%) (2021 Cost Level). The project’s incremental benefit-to-cost ratio is 2.4 to 1 (at the current discount rate of 2.75%).
