(Columbia County) Roughly 75 Wisconsin National Guard Soldiers were sent into active duty to help emplace sandbags overnight along Interstate-90/94 near Highway 33 in Columbia County. Without sandbags, the rising floodwaters and additional predicted rainfall threaten to overtop the intestate and cause lane closures. One lane was closed near Highway 33 while the National Guard emplaced the sandbags. According to the National Weather Service, southern Wisconsin is expected to see additional rainfall Monday night with a break in precipitation Tuesday with more rain on Wednesday. Drivers are encouraged to visit 511wi.gov for current road closure information. Motorists are also reminded to take detours if they come across roadways with standing water. Some preliminary estimates show nearly $51 million dollars in damage to public infrastructure has been reported so far, although that number is expected to change in the days ahead.
