Bayou Plaquemine (Plaquemine Lock State Historic Site)
Plaquemine, Iberville County · Louisiana
Fourteen years of building went into a lock that lifted boats 51 feet. Work began in 1895, and Colonel George Goethals of the Army Corps of Engineers, later chief engineer of the Panama Canal, is credited with the design. Dynamite blasts damaged St. John the Evangelist Church nearby. The lock opened on April 9, 1909 and had the highest freshwater lift of any lock in the world. It closed in 1961 after 52 years, replaced by a larger lock at Port Allen. The National Register listed the site in 1972, and it covers about 19 acres today.
