The Coast Guard has established safety zones along large sections of the Mississippi and Illinois Rivers, essentially closing them to commercial traffic due to high water.
More than 100 barges broke free of their moorings near St. Louis on Saturday. Most of the barges were corralled, but some sank and others collided with a bridge, causing authorities to close it temporarily to make sure it was still structurally sound, according to reports from the U.S. Coast Guard.
Barges have also broken loose near Vicksburg, Miss., and on the Illinois River. The Mississippi River has reopened to traffic in Vicksburg, but the Illinois River safety zone will remain in place until April 30, according to a river conditions update by the Ingram Barge Company.
