Braddock Locks & Dam, Navigation lock and gravity dam on Monongahela River, Allegheny County, United States
The Braddock Locks and Dam structure extends 960 feet across the Monongahela River with two locks measuring 720 feet in length and 110 feet in width.
The original facility began operations in 1905, replacing an 1841 structure built by the Monongahela Navigation Company, and underwent major modifications between 1921 and 1953.
The facility represents a critical component of the Pittsburgh Port District's infrastructure system, enabling continuous commercial navigation along the Monongahela River.
The locks operate daily to maintain a navigation pool and facilitate the passage of vessels, managing an annual cargo volume of 54 million tons through the Monongahela River system.
The landward lock, completed in 1953, held the distinction of being the largest inland lock in the United States until 1959.
