St. Paul, Minn. (AP) — The U.S. Army Corps of Engineers will soon close two of its locks and dams on the Upper Mississippi River for winter renovation and maintenance, according to the corps.
Lock and Dam 3, north of Red Wing, Minn., is to be closed Nov. 22 through March 28, weather and river conditions permitting.
During winter, the upper guide wall will be extended, and improvements will be made to the channel and embankment. The work is part of an ongoing $70 million renovation of Lock and Dam 3, being paid for by the American Recovery and Reinvestment Act.
Lock and Dam 10, in Guttenberg, Iowa, is to be closed Dec. 6 through March 15. The lock will be drained during winter for major maintenance work that’s performed every 20 years on each St. Paul District lock and dam.
Lock and Dam 10 was last drained in 1990.
