DETROIT- 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 ice conditions.
Every year, the Corps uses the winter period to perform maintenance to keep the Soo Locks operating. The Soo Area Office 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 conditions they work in.
