Highway officials in North and South Dakota say roads could remain icy for several days following the latest blast of winter weather.
Although snow totals were less than expected in some areas, the storm was preceded by freezing rain and drizzle that put a coating of ice on roads. And frigid temperatures are forecast for the next several days.
Bruce Nord, maintenance supervisor for the North Dakota Department of Transportation, says wind gusts make it difficult to keep sand and salt on the road.
Nord and Fred Moninger, a highway maintenance worker in Rapid City, S.D., say that salt begins to lose its effectiveness in bitterly cold weather.
"That ice is going to be there for a while," Nord said.
