Current through Vol. 42, No. 1, September 16, 2024
The state highway system shall be functionally classified
under the guidelines and criteria set forth in Volume 20, Appendix 12, Highway
Planning Program Manual, Highway Functional Classification, U.S. Department of
Transportation, FHWA, revised March, 1989. The functional classification of the
system is hereby adopted as established during the National Functional
Classification of 1976 and 1993, and subsequent revisions. Classification of
the system shall be Rural or Urban, based on whether the highway is inside or
outside an approved Urban Area Boundary.
(1) The Rural Functional Classification shall
consist of one of the following:
(A) Rural
Principal Arterial. Rural Principal Arterials include the Interstate System and
other major cross state routes. They provide an interconnecting network to
major urban areas.
(B) Rural Minor
Arterial. Rural Minor Arterials include intrastate routes generally serving
traffic having trip lengths and destinations traversing several counties. They
provide an interconnected network between most larger cities and
towns.
(C) Rural Major Collector.
Rural Major Collectors include important intracounty and some less important
intercounty routes. They collect traffic from the local county road system and
provide feeder service to the minor or principal arterial systems. They also
provide access to most small towns and places not already interconnected with a
higher class of highway.
(2) The Urban Functional Classification shall
consist of one of the following:
(A) Urban
Principal Arterial. Urban Principal Arterials include the Interstate System,
Urban Freeway systems, and other major urban routes that move long distance
type traffic within or through an urban area.
(B) Urban Minor Arterial. Urban Minor
Arterials are generally section line routes that serve as important travel
corridors within an urban area.
(C)
Urban Collector. Urban Collectors are generally routes that disperse traffic
from connecting arterials onto the local city street system within a
residential or commercial development.
