Be careful, the segment is defective, there is unnecessary back and forth at the southern end. In addition, a slightly shorter end would be better to combine with other routes. (Have already submitted a change proposal.)
You can let it roll in the direction of Alschbach. in the somewhat narrower part you should drive a little slower, because the valley is a popular shortcut to Biesingen for drivers.
But the valley is also good to drive uphill.
