To properly name County Roads in Indiana refer to INDOT Roadway Inventory for reference. If the roadway inventory says E County Road 100 N then that would be interpreted as E CR-100 N for the primary name. This name is listed as primary for visual and TTS purposes. We also need to list E 100 N as an alternate so addressing will not be broken. If the road is named please use the name as primary. ie Main St will become the primary name. There is no need for an alt name on a county road if the primary name uses the letters in the alphabet
