Percent Miles of the NHS System with Poor Pavement: 2011 and 2017-2020

Figure

A bar chart showing the percentage of miles of the National Highway System (NHS) with poor pavement by category for 2011, 2019, and 2020. Categories include interstate, non-interstate, and totals for rural and urban areas. Among roadway types, urban NHS non-interstate roads had the highest percentage of miles with poor pavement: 17 percent in 2011 and 24 percent in both 2019 and 2020. The remainder of roadways averaged about 5 percent or less of miles with poor pavement across all three years shown.

Road Classification

Notes:

In the above figure, the total rural and urban NHS categories are a summary of the statistics of both the NHS interstate highways and non-interstate highways in each category including Puerto Rico. No data were reported for 2010 due to a change in the data model, so the data reported for 2011 were used. Poor condition is defined as any pavement with an IRI value greater than 170 inches/mile.
