Elizabeth Locks & Dam, Navigation system in Elizabeth, United States.
Elizabeth Locks and Dam is a navigation system on the Monongahela River consisting of two lock chambers and a concrete barrier that controls water flow. The structure manages water levels across the river to allow vessels to pass through different elevations.
Construction began in 1905 under the U.S. Army Corps of Engineers to improve river traffic. The original structure underwent major changes in the 1920s.
The locks and dam are part of the industrial heritage of the region, helping workers and industries transport goods by river traffic.
The best view of the facility comes from the riverbank or nearby public areas. When visiting, watch for safety signs and follow any staff directions.
A permanent concrete structure replaced the original steel drum weir in 1921, marking an important engineering advancement. This change provided more durable and reliable water control.
