Urban Interstate Pavement Condition

The pavement condition of the urban Interstate system worsened from 2015 to 2016, increasing from 5.02 percent in poor condition to 5.18 percent.

The urban Interstates consist of major multi-lane Interstates in and near urbanized areas. The pavement condition of the urban Interstate system worsened from 2015 to 2016, increasing from 5.02 percent in poor condition to 5.18 percent (Table 12, Percent Urban Interstate Mileage in Poor Condition, 2016, Figure 7). In 2016, 958 of the 18,505 miles of urban Interstates were rated as poor, as compared to 940 poor-condition miles out of 18,730 miles in 2015, the last time this assessment was completed.

Between 2015 and 2016, the percentage of poor urban Interstate mileage increased in 29 states, decreased in 20 states and remained about the same in the one remaining state. The percent of poor mileage changed less than one percentage point in 35 of the states. Hawaii and Rhode Island led the states in reducing poor- condition mileage (by 3.3 and 2.8 percentage points, respectively) while Delaware and California led the states in increasing poor- condition mileage (by 10.3 and 3.4 percentage points, respectively).
