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.
