NATIONAL HIGHWAY SYSTEM LENGTH - 2005 - MILES BY MEASURED PAVEMENT ROUGHNESS

Footnotes

1/ Data are reported as the International Roughness Index (IRI) in inches per mile. Reference: World Bank Technical Paper Number 46, 1986. Lower IRI represents smoother riding roadways.To obtain a comprehensive assessment of pavement condition, additional measures of pavement distress are needed.

2/ May include sections entirely on structures and unpaved miles.

3/ Excludes 770 miles of Federal agency owned roads.

4/ 2004 data used.
