"NOTE:  In 2000, the Federal Highway Administration began reporting road condition for urban minor arterials and urban collectors using the International Roughness Index, if available.  In prior years, data were only available using the Present Serviceability Rating.",,,,,,
"NOTE FOR DATA ON THIS PAGE:  Road condition is based on measured pavement roughness using the International Roughness Index (IRI). IRI is a measure of surface condition.  A comprehensive measure of pavement condition would require data on other pavement distresses such as rutting, cracking, and faulting.  ",,,,,,
