Why were the TN 840 tags not removed from this route? When FHWA approved Interstate status and TDOT changed signage, TN 840 was no more.

Generally speaking, roads designated as freeway are continuous for multiple interchanges, or more than a few miles. This section of ALT 220 has neither.

Mistake on the description. I used a GPS Trace of the new Route 100 Morrisville Bypass to add it to OSM.
