Comprehensive Arterial Road Network Plan (2009)


The latest Johnson County Comprehensive Arterial Road Network Plan (CARNP) was approved by the Johnson County BOCC in June 2009.


The purpose of CARNP is to maximize the use of the existing arterial road system. The plan includes a classification system for County arterial roads with ultimate design standards ranging from two-lane rural section line roads with shoulders to four-lane parkways with landscaping and pedestrian and bicycle paths as well as accommodations for possible future public transit service. The plan identifies the type and location of the future road improvements and shows three different levels of improvements: Type I - Minor Arterials; Type II -Major Arterial; and Type III – Parkways.
