Mapillary images strongly suggest that all the cycleways north of Militärringstraße are oneway. Because of "Radwegbenutzungspflicht" it is actually impossible to allow cycling in both directions as there is a cycleway on the other side of the road. Also, the segregated=yes tag under the bridge (way 156149075) cannot be correct, this is a very narrow sidewalk, no way there is segregation. (One can clearly see sign 240 on mapillary images.)
