Great Lakes Shipping Season Ends
The Great Lakes shipping season is coming to an end as ice makes the waterway unnavigable. The U.S. Army Corps of Engineers have closed the Soo Locks that connect Lake Superior with the lover lakes, for winter maintenance.
The navigation system is maintained by the Detroit District, which includes 95 harbors and the Great Lakes Connecting Channels that join lakes Superior, Michigan, Huron, St. Clair and Erie.
“The Soo Locks is the linchpin of the Great Lakes Navigation System, and it is vitally important that we keep this infrastructure in good working order” said Lt. Col. Robert Ells, district engineer, said in a statement. The Soo Locks consist of four parallel lock chambers: MacArthur, Poe, Davis and Sabin.
During the maintenance period, the Corps will repair MacArthur Lock’s watertight doors and miter gates and install a new air bubbler ice suppression system. The Corps also plans to upgrade concrete and install gate fenders.
At the Poe Lock, engineers will install a new hydraulic system to operate the gates, booms and valves.
The Soo Locks will reopen in March.
