1 Includes state park, state toll, other state agency, other local agency, and roadways not identified by ownership.

2 Roadways in federal parks, forests, and reservations that are not part of the state and local highway systems.

3 Excludes 788 miles of Federal agency owned roads.

4 Includes 274 miles of miscoded non-Interstate functional system length or rural/urban categorization or both.

NOTE: The difference in total miles between tables 1-1 and 1-2 results from the Federal Highway Administration's (FHWA) expansion of sample data to derive estimates of road length by different variables. FHWA considers the length totals in table 1-1 to be the control totals should a single value be required.
