IE., if it is classified as a Collector = Primary Street, Principal Arterial = Major Highway, etc...
When transitioning from urban to rural classification,
keep the '''HIGHER''' of the two classifications to the next intersection with a road classified higher than a street within the next 1- 2 miles. If it is greater than a short distance, keep the classification until the intersection with the next street.
IE., if a roads classification is MH in an urban area, but drops to a mH on the rural map, and the road has an intersection/interchange with another road of PS or greater just outside the urban map , continue to the urban classification to that intersection.
