KEY: R = revised.

a 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.

b Collector is the sum of major and minor collectors (rural only).

NOTES: See table 1-6 for estimated highway lane-kilometers by functional class.

Numbers may differ slightly from previous year's metric tables because a higher precision conversion factor was used. 1 mile = 1.609344 kilometers.
