St. Mary's Falls Canal, Soo Locks, St. Mary's River at Falls, Sault Ste. Marie, Chippewa County, MI
Summary
Significance: The locks of the St. Mary's Falls Canal reflect a national level of significance in settlement, transportation, industrial, and engineering history. The completion of the State Locks in 1855 effectively opened to settlement the territory surrounding Lake Superior. Prior to that , large-scale settlement of the region was impractical. Ultimately, it was discovered that the land made accessible by the canal was rich in copper and iron ore. These deposits fed the nation's industrial revolution in the latter portion of the nineteenth century. Naturally, the primary method of transporting large amounts of this mineral wealth was through the St. Mary's Falls Canal. Until the 1950s, the fleet serving the Great Lakes made the Sault Canal the busiest waterway in the world. Due to dramatic growth of shipping on the Lakes, the St. Mary's Falls Ship Canal has received constant attention by the U.S. Army Corps of Engineers over its history. Between 1881 and 1969, the Corps constructed six locks on the American side of the Sault. Each of the facilities embodied the most advanced form of lock technology known at the time of their construction. Additionally, several of the structures were designed as the largest in the world at the time.
