A collector road connects a local road with an arterial road.
A marginal road is parallel to a freeway or arterial road and provides access to local roads.
A residential light traffic road is a dead-end road, less than three-fourths of a mile in length, including a side street.
A residential medium traffic road is a dead-end road, greater than three-fourths of a mile in length, including a side street, or a road passing through a residential area but out of line of through traffic.
Commercial and industrial park roads are roads in subdivisions having commercial and/or industrial enterprises served by trucks.
In case of a question, the Street Commissioner will decide on the road class for construction purposes.
Pavement width for all road classes is for roads without on-street parking. Add ten feet in width for each parallel parking lane if the road is designated for street parking.
