(sorry, my German is not good enough to write this coherently)

further to the other note - the mapped location of the roundabout is not quite accurate. East-west is approximately correct, but. the entire new build of the roundabout is north of the existing road. The pavement continues on the old alignment, but the old road bed has been dug up and replaced by earth.

This is unlike the roundabout at the other end of the L2070, which has been built over the existing road (there the existing road was closed for months - here the roundabout was completed, then the traffic moved onto the new alignment, one lane at a time, controlled by temporary traffic lights)
