Approximately one percent of all public roads are part of the Interstate Highway System. Of these 47, miles of Interstates, 65 percent are in rural areas and 35 percent are in urban areas. Seventy-four percent of the remaining public roads are located in rural areas, with 26 percent in urban areas.
Since an additional , miles of public roads have been constructed, an average of 6, miles of new roads each year. Rural public roads have steadily decreased since as these roadways have been reclassified as urban due to increases in population and geographic dispersion.
At the same time a corresponding increase in urban facilities is seen partly due to urban boundary reclassification and partly due to new construction. Note: Lane-mile data not available before In there are 4. Centerline miles increased 0.

The highway continues beyond the intersection as the Kalanianaole Highway state route The formal end of H-1 is marked by the faded terminal milepost in the photo on the right, with a horizontal "44" under the vertical "27" barely visible, even with digitally enhanced contrast for the very faded milemarker in this photo to indicate that the route ends at mile The exact north end of Interstate H-2 is just before the yellow "end freeway" overhead sign, and driveways for some of the establishments serving soldiers at the adjacent Schofield Barracks Army base.
