eeh, what "what end" ? Either the highway line is linked to another highway
at both ends, then "noexit" is a tagging mistake. Or the highway line is
not linked to another highway on both ends and then the "noexit" can be
helpful (confirming tha'ts really an isolated highway and not some
connection missing)
