       | As always with this kind of stuff, there are so many
       | inaccuracies, at least in the parts I know of. Roads are mostly
       | ok, although some of them are more like "suppositions" that real
       | roads we have found. Let's take a look at the area around
       | Valladolid: https://imgur.com/xMW6yiY
       | 
       | - Pintia is almost confirmed to be near the Duero/Douro river,
       | much more to the south and to the east. It is one of the most
       | explored pre-Roman settlements in the area and while there has
       | not been a definitive proof, there are many hints that show that
       | it's on the place I showed and not where it's shown on the map
       | 
       | - Amallobriga is also, for most historians, located in Tiedra,
       | but it shows Tordesillas. As you can see on the map, the actual
       | location of Tiedra is also a road intersection. The location in
       | Tiedra is consistent with archeological evidence and with route
       | books that show the distance from Amallobriga to other cities we
       | know.
       | 
       | - Nobody really knows where Intercatia or Tela are. But note that
       | a there's a big road intersection at the south. It is confirmed
       | that there was a settlement but we do not know the name of it,
       | several have been proposed. In any case, Intercatia is very
       | difficult to be located as it is shown in the map with no roads
       | going to it. Many archaeologists say it could be in the actual
       | town of Paredes de Nava.
       | 
       | - I don't think there's any real evidence of a bridge that
       | crosses the Douro/Duero river there. What we know is that there's
       | a medieval bridge closer to Septimanca and that it could have had
       | a Roman origin, but according to the map there's no road there.

         | I was wondering the same thing about the road crossing the
         | Douro between present-day Vila Nova de Gaia and Porto. Was
         | there a bridge there during Roman times? Interestingly, it
         | would be right where the Luiz I Bridge is now.

           | After a quick research, there's no evidence of a bridge there

           | river and still be considered part of the road.

       | 
       | Two macroscopic problems are:
       | 
       | 1. The only variant given is between Bolsena and Fabro. There is
       | nothing about later routes to the west of Valdichiana and to the
       | left of the Arno.
       | 
       | 2. The section between Arezzo and Cascia used the exact route of
       | the modern Setteponti, which was certainly not the case.
       | 
       | Beyond these errors, every section I have checked in detail for
       | the Cassia contains inexact info.

       | Interesting, but it'd be even better if it was the OpenStreenMap

       | collaborative effort could fix that.
       | 
       | You can click on a road segment and get some info about it so the
       | first step would be to add a way to contact its author to suggest
       | improvements.
       | 
       | For example I know of some hidden ruins of a very ancient bridge
       | where my local roman road crossed the river with two paths that
       | show where the road on both sides would have been instead of
       | where the road cross the river on the segment.

       | For my part, the Romans never went more than halfway up the
