The U.S. Army Corps of Engineers, Detroit District, removed a spare set of miter gates, constructed for the Davis and Sabin Locks, from the St. Marys River this summer. The miter gates were hidden in the river for over 80 years and weighed about 350,000 pounds each.
The gates were strategically stored downriver of the Soo Locks facility and out of the federal navigation channel in the 1940s during World War II. The purpose of storing the gates downriver was to have a spare set of replacement gates for either lock if the installed gates were damaged.
“The Davis and Sabin locks were built in 1914 and 1919 and at the time were the largest locks in the world,” said Chief Park Ranger Michelle Briggs.
