b  Included in row below.,,,,,,,,,,,
,,,,,,,,,,,
NOTES,,,,,,,,,,,
Numbers may not add to totals due to rounding.,,,,,,,,,,,
Interstates have stricter roughness standards than other roads and its roughness classifications are not comparable with the other categories.,,,,,,,,,,,
"Data are for the 50 states and the District of Columbia.  The terms poor and mediocre as used here are Federal Highway Administration (FHWA) pavement condition criteria term categories for quantitative International Roughness Index and Present Serviceability Ratings.  For further information, see U.S. Department of Transportation, FHWA, Status of the Nation's Highways, Bridges, and Transit: 2002 Conditions and Performance Report, Exhibit 3-3, available at: http://www.fhwa.dot.gov/policy, as of November 2008.  ",,,,,,,,,,,
"Comparisons of data between pre-1993, and 1993 and later years are difficult because of the transition to a new pavement condition indicator beginning with data published in 1993. Thus, trend comparisons should be made with care. For additional information, refer to the accuracy profile for this table in the appendix. Total mileage in this table will not match that in table 1-5 due to a change in the method of preparing mileage data derived from the Highway Performance Monitoring System, beginning with the 1997 issue of FHWA's Highway Statistics.",,,,,,,,,,,
