1/ Includes the 50 States, the District of Columbia, and Puerto Rico. Some differences from other tables may be noted because these are estimated from sample data and do not include samples entirely on structures. Indiana may exclude up to 788 miles of Federal agency owned roads. Minnesota excludes 437 miles of local government owned roads.

2/ Differences may exist from prior years due to a redefinition of divided and undivided roadways in 1999.
