  • Certain Well documented, mapped to within about 50 to 200 m
  • Conjectured Known road, course less precisely documented
  • Hypothetical Route not pinned down, or existence uncertain
  • Secondary road Thinner line, any certainty

How accurate are these lines? Most Roman road routes on this map are approximate. The Itiner-e project, which supplies the data, classes most of them as Conjectured, so read a line as a best estimate of where the road ran rather than a surveyed route.
