  • 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.

About the Via Domitia

None of the Via Domitia is classed as certain: almost all of it is conjectured, so the line on the map is a best estimate of the course rather than a surveyed route.
