- 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.
Also it is high time for everyone to understand that not every map out there is goog's and more importantly - there are at least 5 providers of mappings software that do it either better or likewise well, and these guys' work needs to be respected. In fact it is very likely that gmaps would rate very low if one is to rank it considering usability (APIs including), licensing, speed and quality of the render.
the Google Maps is being used to frame or position the sites intent of a data rich maps site of Roman Roads
"Itiner-e – The Digital Atlas of Ancient Roads"
And Goog does none of this to deserve any credit.

I wonder if there's a missing roman settlement under Sarajevo, considering the roads there match so well and the size of the city.
Unfortunately, Brughmans, de Soto, and Pažout neglected to include the legally required attribution for this use of OpenStreetMap data (via Mapbox). This is a shame, because these kind of projects are great to show people that there is more than just Google Maps.
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.
A bit of work on the UI would make this a really fun and interesting tool - currently it seems to be intended for people who know a lot about the dataset already.
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.
