Main Channel Bridge (Winona) is a cantilever bridge that spans the main channel of the Mississippi River in the United States between Winona, Minnesota and Latsch Island. Another bridge, the North Channel Bridge, connects the island to rural Buffalo County, Wisconsin. Construction on the Main Channel Bridge was started just before the U.S. entered World War II, and the construction was hastened to finish in November 1942, despite labor shortages, difficulty obtaining materials, and high water. It was built in 1941-1942 by the Minnesota Department of Transportation (MnDOT).

The existing bridge will be rebuilt and strengthened so that it can be used for many more years to come.
