I encountered this issue too. An overpass near me was demolished but Google Maps was still showing it there. I submitted an edit and included a link to the state DOT's website about the project that clearly stated the overpass would be permanently demolished and not replaced. My edit was rejected.

Who would be able to do that if not a judge?
