That is a non-sequitur. The ways exist and have been mapped. The route,
which consists of those ways, has been marked as conjectural. How
much of it is conjectural could be a very tiny fraction of it.

however, a road improvement (using machinery unavailable to the Romans)
includes a slight diversion. Sometimes the diversion retains the name and
the original route is prefixed with "Old." Mainly, though, the routes of
go back many centuries to days when they were little more than cart tracks.
