Wiley-Dondero Canal

The United States Army Corps of Engineers planned and supervised the Wiley-Dondero Canal to bypass the Long Sault. Actual construction was performed by Peter Kiewit Sons Co., Morrison-Knudsen Co., Perini Corp., Utah Construction Co., and Walsh Construction Co.

Located near Massena, New York, the seaway provides a total lift of 83 feet (25 m) from the Eisenhower Lock and the Bertrand H. Snell Lock, which are the two locks in the canal.

Originally known as the Long Sault Canal, it was later renamed the Wiley-Dondero Canal. Construction was complicated by the need to avoid interrupting the waterflow to nearby hydroelectric installations.
