The U.S. Army Corps of Engineers, Detroit District will open the Poe Lock, part of the Soo Locks, in Sault Ste. Marie, Michigan early to all marine traffic at 8 a.m. on March 21, marking the start of the 2025 Great Lakes shipping season.
The shipping industry requested an early season opening based on the understanding that “the 2025 winter lock maintenance will be completed by this date and an early opening will not impact U.S. Army Corps operations this season,” said Lake Carriers’ Association President James Weakley.
“Opening the Soo Locks on March 21 will provide relief to the increased pressure that the Great Lakes Navigation System will face with the influx of foreign vessels including the Canadian domestic fleet on March 22 when the Seaway opens,” said Weakley.
