Certified Public Road Miles (CPRM)

The Federal Highway Administration (FHWA) requires ADOT/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. 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.

Transportation Data Services collects CPRM milage information from State agencies, Borough and municipal governments. The CPRM report also includes mileage reported by Federal, Tribal and other government agencies in the State that maintain public roads.
