Lockport in Niagara County, New York — The American Northeast (Mid-Atlantic)
“Lockport Flight of Five”
To overcome the great elevation of the Niagara Escarpment, the original canal builders constructed a unique flight of 5 double locks, to lower easterly and raise westerly bound boats some sixty feet.
The Erie Canal was constructed in three historic stages: the original Erie Canal, or Clinton’s Ditch, 1817-1825; the enlarged Erie Canal, 1835-1862; the New York State Barge Canal System (Erie Canal Division), 1905-1918. Here in Lockport, the present day Erie Canal follows basically the same course as the original and enlarged 19th century canals.
To overcome the great elevation of the Niagara Escarpment, the original canal builders constructed a unique flight of five double locks, to lower easterly and raise westerly bound boats some sixty feet. The original locks of 1825 were replaced by a larger flight of double locks constructed between 1836 and 1847. These locks were numbered 67 to 71. The enlarged combined locks were replaced by Locks 34 and 35 of the Barge Canal Improvement between 1910 and 1914. The northern set of the “Lockport Five” was left intact and today is used as a spillway.
The old “Lockport Five" and Locks 34 & 35, provide splendid examples of the historic evolution of the New York State Canals in the 19th and 20th centuries.
