System Mileage by Functional Class
includes National Highway System (NHS) and
Principal Arterial System (PAS) (RI - 339)

Each page consists of one county with total centerline roadway mileage divided by state, county, township, and municipal jurisdictions. The state is further divided by interstate, U.S. and state routes. There is a total for all state routes and a grand total for all systems. The National Highway System (NHS) and the Principal Arterial System (PAS) — not already on NHS — are also included with totals. The mileage is broken down by Functional Classification for each system with totals. At the end of the report there are statewide totals for all categories.
