FUNCTIONAL CLASSIFICATION

One of the most important programs for the CAAG Region is the five-year TIP.  The CAAG Region currently receives approximately $1.8 million per year for construction and reconstruction of local roads.  In order to be eligible for inclusion in the CAAG TIP, a road has to be Functionally Classified in the Federal Roadway System.

CAAG assists member entities in submitting requests for Functional Classification on an ongoing basis.  These requests are reviewed and submitted to ADOT and ultimately go to the Federal Highway Administration for final approval.

The Functional Classification System has recently been updated and changes will be input as road classifications continue to change.  The classifications currently in use are:

• Rural Principal Interstate
• Rural Principal Other
• Rural Minor Arterial
• Rural Major Collector
• Rural Minor Collector
• Urban Principal Interstate
• Urban Principal Freeway or Expressway
• Urban Principal Other
• Urban Minor Arterial
• Urban Collector
