Critical Arterial Corridor Policy

The Critical Arterial Corridors (CAC) are identified and established to protect the long term integrity of transportation facilities that provide regional transportation access across the Coeur d’ Alene Urbanized Area, as well as provide direct access to the State and National Highway System.

The need for a Critical Arterial Corridor Policy has been identified as a result of growth and development activities that have sought to develop and request access onto regionally significant arterials. These regionally significant arterial corridors have, or are intended to be designed for higher speed (35 mph and above) facilities, where access is intentionally limited in order to protect and maintain the safe and efficient regional movement of people and goods. Managing access reduces travel times and fuel costs, while improving safety for the public.

The Policy on the Identification, Establishment and Protection Of Critical Arterial Corridors Within and Effecting the Coeur d’ Alene Urbanized Area and Critical Arterial Corridors Map were adopted by the KMPO Board on May 9, 2019.  Both documents will be reviewed, at a minimum, every three years to reflect changing conditions.

The purpose of this policy is to establish area wide guidance on the identification and establishment of access controls, as well as access treatments onto arterials within the federally designated urbanized area of Kootenai County.
