Improved highway design that directs drifting snow off the road is helping the North Dakota Highway Department reduce its annual installation of snow fencing from 400 miles down to eight miles. Most of the highways today have a 4:1 slope and a minimum of 12-ft. ditch bottom. Briefly, to design changes that have resulted in reduced needs for snow barriers are as follows: flatter and rounder slopes to provide less obstruction to drifting; streamlining the cross section at the transition of cut to fill; and giving special consideration in known snow problem areas. Reduced mowing has provided vegetation in the ditch bottoms which results in a smooth transition for the snow to clear the entire roadway and ditch.
