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 and it seems difficult to do even for Romans. But there could have been some people with boats in Cale to help cross the river and still be considered part of the road.
I know that not too long ago there was a "bridge", which was a bunch of boats aligned from one margin to the other. Not sure if this counts as a bridge.
