Final Freighter Passes Soo Locks Before Winter Closure
The Soo Locks in Sault Ste. Marie, Michigan, officially closed for the winter shipping season on January 15, 2026, after the last vessel, the American Spirit, completed its passage. The 1,004-foot-long freighter carried over 51,000 tons of iron ore destined for Conneaut, Ohio. The U.S. Army Corps of Engineers reported that the ship navigated through heavy ice conditions, highlighting the challenges faced during the winter months.
Winter Maintenance Underway at Soo Locks
The Soo Locks, crucial for shipping between the Great Lakes, will remain closed until March 25, 2026, to allow for essential maintenance work. This annual closure enables the U.S. Army Corps of Engineers to perform critical repairs and upgrades on the locks. Operations Branch Chief Jeff Harrington emphasized the dedication of the maintenance crews, who work long hours under harsh winter conditions to ensure the locks are ready for the upcoming shipping season.
This year, the MacArthur Lock will not be dewatered, and its closure will depend on weather and ice conditions. Maintenance tasks include fabricating and replacing components for various gates, conducting inspections, and performing concrete repairs. The Poe Lock will also undergo significant maintenance, including inspections and repairs to ensure its functionality for the busy shipping season ahead.
Earlier on January 15, the Clyde S. VanEnkevort/Erie Trader was the second-to-last vessel to pass through the locks, transporting iron ore from Duluth, Minnesota, to Cleveland, Ohio. The Soo Locks typically see over 7,000 ship passages during the navigation season, underscoring their importance to the regional economy.
Significance of the Soo Locks
The Soo Locks consist of two canals and four locks that facilitate the movement of vessels across a 21-foot elevation drop between Lake Superior and the lower Great Lakes. The locks are vital for the transportation of goods, particularly iron ore, which is essential for the steel industry. The construction of a new lock, expected to take up to ten years and cost approximately $3.22 billion, is currently underway to enhance the capacity and efficiency of the facility.

As the locks prepare for their winter maintenance period, the U.S. Army Corps of Engineers continues to communicate with industry stakeholders to ensure a smooth transition into the spring shipping season. The reopening of the locks marks a significant event for the Great Lakes shipping industry, which plays a crucial role in the U.S. economy.
