Elizabeth Locks & Dam, Navigation system in Elizabeth, United States.
The Elizabeth Locks and Dam consists of two lock chambers and a concrete dam spanning the Monongahela River at mile marker 23.8.
Construction of the facility began in 1905 under the U.S. Army Corps of Engineers, replacing an earlier structure built by the Monongahela Navigation Company.
The Elizabeth Locks and Dam represents the industrial heritage of Pennsylvania, enabling commercial navigation between Pittsburgh and West Virginia through the Monongahela River.
The facility maintains a navigation pool extending 23.8 miles upstream to Charleroi, Pennsylvania, allowing vessels to navigate through different water levels.
The dam includes a fixed concrete crest that replaced the original Chittenden steel drum weir in 1921, marking a significant engineering modification.
