In 1913, the Army Corps launched construction of Troy's Federal Dam, using engineers experienced on the Panama Canal. 113 years later, the lock and dam still supports New York's Hudson River navigation and remains a landmark of American engineering

Troy Lock and Dam : For more than a century, a major engineering project has stood along the Hudson River in Troy, New York, helping support navigation between the river and the state's canal system.

Construction of Troy's Federal Dam began in 1913, when the Army Corps of Engineers removed an older state dam and built a new federal dam with a lock channel about 1,000 feet upstream from the original site, as per a report. The project brought together Army engineers and contract laborers, many of whom came to Troy after completing work on the Panama Canal.
