KEY: N = data do not exist; - = value too small to report.
a Historical differences in miles not reported result from the transition from the Present Serviceability Rating (PSR) to the International Roughness Indicator (IRI).
b Included in row below.
NOTES
Because of the transition to a new indicator for pavement condition beginning with U.S. Department of Transportation, Federal Highway Administration (FHWA) data published in 1993, comparisons between pre-1993 data and 1993 and later data are difficult. Thus, trend comparisons should be made with care. For additional information, the reader is referred to the accuracy profile for this table in the appendix. Total mileage in this table will not match that in table 1-5 because of a change in the method of creating mileage-based tables derived from the Highway Performance Monitoring System, beginning with the 1997 issue of FHWA's Highway Statistics.
Data are for the 50 states and the District of Columbia.
Numbers may not add to totals due to rounding.
