SAULT STE. MARIE, Mich. - The Soo Locks in Sault Ste. Marie, Michigan will close to all marine traffic beginning 11:59 p.m. January 15, or until commercial traffic ceases, through 12:01 a.m. March 25 to perform seasonal critical maintenance.
Federal regulation (33 CFR 207.440) establishes the operating season based on the feasibility of vessels operating during typical Great Lakes ice conditions.
“Every year, the Corps of Engineers uses the non-navigation winter period to perform maintenance and keep the Soo Locks operating,” Maintenance Branch Chief Nicholas Pettit said. “The Detroit District team works long hours in extreme conditions to complete a significant amount of maintenance during this annual closure period. The work they perform is unique, especially given the harsh northern Michigan winter conditions they work in.”
