The U.S. Army Corps of Engineers says the final vessel passed through the Soo Locks yesterday evening in Sault Ste. Marie.
The season’s final vessel, the 767-foot Cason J. Callaway passed through the locks after 6 p.m. Tuesday, downbound with 25,000 tons of taconite pellets. During the 2012 navigation season, just over 4,000 cargo vessels passed through the locks carrying about 75 million tons of cargo vessels.
The Corps has operated and maintained the locks as part of its navigation mission since 1881 and will use the downtime to perform critical winter maintenance on the lock structures.
