While the sun was shining down and drying out roads and fields, the National Guard returned to the interstate to stack sandbags and attempt to hold back the rising Baraboo River. The ramps from Highway 33 to Interstate 90/94 were closed Thursday while trucks from the National Guard dropped off pallets of sandbags. The pallets then were picked up by forklifts to be delivered at unloading sites north of the exit along the interstate. About 150 National Guard members arrived in Columbia County to build a 4,000-foot-long barrier along the interstate with roughly 24,000 sandbags, according to the Wisconsin Department of Military Affairs.
