Bitter cold has returned to parts of the Midwest, mid-Atlantic and Northeast, following another heavy snowstorm that left 1 to 2 feet of snow from Ohio to New England.
And when all this snow finally melts, it'll expose the physical toll of this brutal winter: potholes, broken water mains, collapsed catch basins and other infrastructure problems.
"This winter's crazy, crazy busy," says John Polishak, a foreman for the Chicago Department of Water Management. "Everybody's been working 16 hours a day, seven days a week. It's exhausting."
