No Autobahns, though..............
There were also (as there are now) vicinal roads, which were not up to Roman military standards. Some existed earlier and continued in use, some developed over time as local shortcuts or routes to places which had started to thrive.
On the campus where I once spent the tail end of growing up, footpaths worn by shortest-route-seekers would often be given the sidewalk treatment, if not, a barrier would be erected over the summers and the path reseeded.
I had the same reaction.
