KEY: R = revised.
a Includes the 50 States and the District of Columbia.
b For urban: the sum of other freeways and expressways, other principal arterials, and minor arterials. For rural: the sum of other principal arterials and minor arterials.
c Includes minor and major collectors.
NOTES
1 mile = 1.609344 kilometers.
In estimating rural and urban lane kilometers, the U.S. Department of Transportation, Federal Highway Administration assumes that rural minor collectors and urban/rural local roads are two lanes wide.
Beginning in 1998, approximately 222,733 lane-kilometers of Bureau of Land Management roads are excluded.
