Second Poe-Sized Lock

The image above is an Artist Rendition that illustrates what it might look like if a Second Poe-Sized Lock replaced two of the older locks (left portion of the photo). The Poe Lock, opened in 1969, was the last lock built in the Soo Locks system, the only passage between Lake Superior and the lower lakes.

The Soo Locks facility, operated and maintained by the U.S. Army Corps of Engineers, Detroit District, is the District’s largest project and is located on the St. Marys River at Sault Ste. Marie, Mich. on the international border with Canada. Approximately 80 million tons of commercial commodities pass through the Soo Locks annually.
