The condition of roads in the United States improved between
1993 and 2001.1 For instance, the percentage of rural Interstate
mileage in poor or mediocre condition declined from 35 percent
in 1993 to 14 percent in 2001 (figure 83). Moreover, poor or
mediocre urban Interstate mileage decreased from 42 to 28
percent over this period (figure 84). Just over 40 percent of
all U.S. urban and rural roads were in good or very good
condition in 2001, while nearly 19 percent were in poor or
mediocre condition. The rest were in fair condition. See chart
for Highway Functional Classification System 1 The data
presented here start at 1993; in that year the Federal Highway
Administration changed to a new indicator for pavement
condition. Thus, combining pre-1993 data and 1993 and later data
is inappropriate. 2 These percentages include all classes of
roads except local roads or minor collector roads.
