In my opinion, one of the most bicycle-unfriendly cities on the Main is Gemünden.
If you come on the Mainradweg from Karlstadt, you have to go through the railway underpass and you are in front of the very busy B 26. You have to cross this using a traffic light. There is almost no installation space on either side of the street. If several cyclists want to cross the street, you can save yourself in the underpass on one side. On the city side, however, there is immediately a crowd grid. This is long and narrow. Driving through is really fun with a trailer. The pedestrian zone begins immediately, where cycling is prohibited with a corresponding traffic sign. After a few meters, the road leads to Obertorstraße, where cycling is permitted again and even cars drive around. But you can't see this, because the corresponding signs are only at the other end of the street. Then there is the “wonderful” cobblestones. If you decide to drive instead of pushing, you almost get a tangled bowel.
To continue on the Main Cycle Path, you have to cross the Saale Bridge at the fish market. There is no bike path here either. Would be very desirable in the dense traffic.
Another point is the journey to the train station. You can use the sidewalk up to the level of the Nettomarkt. Then it is forbidden to continue driving. In addition to the heavily frequented exit and entrance to the Nettomarkt, there is also a road junction and the busy main road. Here you have to take the main road to get to the train station on the other side of the road, which is within sight.
A well thought-out cycle path concept looks different. In particular, because the very busy Mainradweg leads right through Gemünden.
