Alton, Ill.-Citing bitter cold and ice buildup on some Mississippi River locks and dams, the Army Corps of Engineers on Feb. 5 announced limits on the widths of barge tows on nearly 100 miles of the river, from Clarksville, Mo., south to near St. Louis. That directive came two days after a 15-barge tow got stuck in the 1,200-foot-long main chamber of a lock and dam near Alton, Ill., forcing the closure of the main chamber for several hours until other tow boats could free the trapped tow.
