City of Bethany and MoDOT road crews spent the weekend digging out from a major snowstorm that hit on Friday night and continued almost without letup until Saturday evening.About 10 inches of the white stuff were measured at some locations in Bethany. The snowfall was even heavier in central Missouri where about 17 inches fell, closing the University of Missouri campus and shutting down the Columbia Regional Airport when a passenger plane slipped off the runway.
