SAULT STE. MARIE, Mich., - The Soo Locks’ MacArthur Lock will close to marine traffic 7:00 a.m. Dec. 17, 2022, through 12:01 a.m. April 24, 2023, to perform critical maintenance.
The Poe Lock will remain open until 11:59 p.m. Jan. 15, 2023, or until commercial traffic ceases, whichever occurs first. The operating season is fixed by federal regulation and is driven in part by vessel operability in typical ice conditions.
“The 800-foot-long MacArthur Lock, built in 1943, is 79 years old; the maintenance period is critical to keeping the lock in operation during the shipping season,” Maintenance Branch Chief Nicholas (Nick) Pettit said.
Pettit, new Maintenance Branch Chief at the Soo Locks will oversee the team executing this year’s seasonal repairs.
