This is an issue with a route, not about a technical problem. I use PS4, but I guess this will happens on all platforms. I found there is a missing bridge on the Koln - Aachen route! Check these pictures: As shown on the red square it is located 40 kms from Koln. I do not know if was already reported, but just in case I would like to do it anyway. Just wants to collaborate with DTG.
