The lanes of this road are separated for most of its length. I only corrected the qualification of a part of the road that was different from the rest, even though it looks exactly the same. It looks like I really requalified it wrong, but that means the rest of the road I didn't fix was wrong.
The "trunk" tag should be from the intersection with Wildsdruffer Straße near Kesselsdorf to the intersection Fröbelstraße with Waltherstraße in Dresden.
I looked at the fact that in the history of this road, the qualification changes very often. The "primary" and "trunk" tags were often interchanged.
If you believe that this road should really be marked as a "trunk", you can start requalifying it along the entire mentioned length.
