A dire warning tonight about what could happen if one of the locks or dams on the Mississippi River fails.
There are 25 aging locks and dams on the Upper Mississippi.
Each day during the shipping season, the river is dotted with massive barges going up and down the river.
A new study shows between Winona and La Crosse, the locks and dams are more than 80 years old.
Should river shipping be halted because of a lock or dam malfunction, it could mean shippers would have to use trucks.
It could take 600 more trucks a day on Highway 52 through our area to transport that material.
The U.S. Army Corps of Engineers says it is behind on maintenance of the locks and dams.
