Good background definition on County Roads: https://en.wikipedia.org/wiki/Numbered_roads_in_Indiana#County_Roads_in_Indiana |
See Indiana/Special roads for guidance in Indiana that may not be universal to all other states and territories.
Alleys
Alleys may be mapped if any of the following is true:
- They are needed for residential access (e.g. one or more rear-entry garages or the primary access to a residence is on the alley)
- The primary access to a business is via the alley
Alleys should be marked as Parking Lot Road and named "Alley", with the appropriate city selected per usual.

Indiana deviates from the GLR/National standard here. The Indiana policy is to set the speed limit to the lowest speed limit among the feeder roads for the roundabout
