principal arterials, and minor arterials.
For rural: the sum of other principal arterials and minor arterials.
c Includes minor
and major collectors.
d Beginning in 1998, approximately 86,000 lane-miles of Bureau
of Land Management roads are excluded.
NOTE
In estimating rural and urban lane mileage, the U.S. Department
of Transportation, Federal Highway Administration assumed that rural minor
collectors and urban/rural local roads are two lanes wide.
