Road Conditions Lead To Shake Up At St. Paul Public WorksOne of the Twin Cities is getting new snow plows and new leadership after last week's snowstorm. Five days since the snow started falling, streets in Minneapolis and St. Paul are still caked in slippery ice. Extremely cold temperatures haven’t helped. Salt can melt five times as much ice at 30 degrees as at 20 degrees. However, when it's colder than that, it's pretty much useless. But St. Paul Mayor Chris Coleman isn't waiting for a warm-up. He's making changes in his public works department.
