SAULT STE. MARIE, Mich., - The Soo Locks in Sault Ste. Marie, Michigan will close to marine traffic beginning 11:59 p.m. January 15 through 12:01 a.m. March 25 to perform critical maintenance.
The operating season is fixed by federal regulation and is driven in part by the feasibility of vessels operating in typical Great Lakes ice conditions.
“It is a difficult time in terms of weather to complete this work, but it keeps this important national infrastructure project operating during shipping season,” Soo Area Engineer Kevin Sprague said.
