Maritime Museum
The Soo Locks in Michigan, located on the St. Marys River between Lake Superior and Lake Huron, are a critical engineering marvel that enable ships to bypass the 21-foot rapids of the river by raising and lowering vessels between different lake levels.
Dating back to the mid-1800s, the locks facilitate shipping of nearly 86 million tons of cargo annually, including 95% of the United States' iron ore, connecting the Great Lakes to international markets. The locks system includes the operational Poe Lock, rebuilt in 1968 to accommodate large modern ships, and the MacArthur Lock, with others like the Davis and Sabin Locks no longer in use.
The U.S. Army Corps of Engineers has managed the locks toll-free since the 1880s. A new, similarly sized lock is under construction to improve capacity and reliability, with a projected completion around 2029, vital for the regional economy and national security.
Adjacent to the locks, the Soo Locks Visitor Center and nearby museums provide historical exhibits and educational information about the locks’ importance and history to thousands of visitors each year.
