Public Road Length, Miles by Ownership


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.


1 Includes state park, State toll, other state agency, other local agency and other 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 Data for Puerto Rico are for 2009.
