Without looking at the URL, because I know I would get confused by an interminable and confusing debate, and answering on general principles...
a) If the DoT issues or maintains these designations, which one would assume it does, then their sources are to be preferred when there's a discrepancy - the higher on the chain the source is, the less likely it is for transmission errors or copyright traps* to sneak in.
-but-
b) if there is reason to believe the authoritative source may be incorrect, for example if the map dates from 1970 or if it happens to miss out a city for no apparent reason, cite both and briefly discuss.
"The Department of Transportation gave the end of the designated area as X in a 1975 publication [1], though more recent sources have suggested it may extend as far as Y [2]. A more recent DoT source is not currently available to clarify this."
