G9 is not existing anymore. Traffic is rerouted to the new A4 (only 1st carriageway in service right now) which is almost concurrent with the old G9 alignment. I don't know if we should change it now (I would) or if we should wait till the 2nd carriageway will be opened "anytime soon" (maybe by the end of year or in early 2019). Nevertheless, OSM is already clearly showing the new route.
