A public road is any road under the ownership of and maintained
by a public authority (federal, state, county, town or township, local
government or instrumentality thereof) and open to public travel. No
consistent data on private road mileage are available. For more detailed information, including
breakouts of mileage by ownership and type of surface, see the source
document.
