Emergency Services Director Mitchell Byrd said some problems were reported at the Cape Fear River Bridge and the Tar Heel Ferry Bridge.
A number of minor accidents were reported between 5-7 a.m. Monday. No serious injuries were reported.
Byrd said the bridges were clear after N.C. Department of Transportation crews spread salt and sand across the icy roadways.
No power outages were reported, Byrd said, but schools, including Bladen Community College, delayed opening by two hours.
A heavy rain system turned to sleet, freezing rain and ice Sunday night as temperatures dropped just below freezing. Byrd said most of the problems were along the Sampson and Cumberland County lines, in the northern sections of the county.
A light layer of ice coated many trees by 8 a.m. Monday, and car windows were covered by as much as 1/2 inch of frozen precipitation.
The change came as a shock after Saturday's temperatures reached into the lower 60's in some areas, with highs in the 50's.
The storm system has dropped as much as two feet of snow in some northern states, and snow and ice were crippling areas west of I-95 Monday.
