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

3Data for Puerto Rico are for 2009.

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.
