Certified Public Road Miles (CPRM)

The Federal Highway Administration (FHWA) requires Alaska DOT&PF to provide an annual report of public road miles in Alaska. Public road mileage is one of several variables that FHWA uses to determine funds for state transportation programs. A public road is any road under the jurisdiction of and maintained by a public authority, open to the general public, and passable by standard passenger cars. CPRM reports are used to populate the FHWA highway statistics publication. CPRM is also used in many department reports and publications.

The Transportation Information Group (TIG) collects CPRM mileage from State and Federal agencies, Indian nations, Boroughs and city governments.
