KEY: R = revised.

^a Includes the 50 States and the District of Columbia.

^b Urban other arterial includes other freeways and expressways, other principal arterial, and minor arterial. Rural other arterial includes other principal arterial and minor arterial prior to 2009, and includes other freeways and expressways, other principal arterial and minor arterial for 2009.

^b Collector is the sum of major and minor collectors.

NOTES

See table 1-6M for estimated highway Lane-kilometers by functional class.

1 mile=1.609344 kilometers.

Component values may not add to totals due to rounding.

2009 data exclude 1,325 kilometers of federal agency owned roads and 114 kilometers of other non federal agency owned roads. 2008 data exclude 1,268 kilometers of federal agency owned roads. 2007 data exclude 1,268 kilometers of federal owned roads and 703 kilometers of local government owned roads. 2006 data exclude 1,268 kilometers of federal owned roads and included 441 kilometers of miscoded roads. 2005 data exclude 1,239 kilometers of federal agency owned roads.
