The U.S. Army Corps of Engineers says it will soon close two of its locks and dams on the Upper Mississippi River for winter renovation and maintenance.

Lock and Dam 3, north of Red Wing, Minn., is slated to be closed Nov. 22 through March 28, weather and river conditions permitting.

During the 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 funded by the American Recovery and Reinvestment Act.

Lock and Dam 10, in Guttenberg, Iowa, will be closed Dec. 6 through March 15. The lock will be drained during the 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.
