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.

Google’s editing algorithm is atrocious.

I’m a local guide, although I haven’t really done much in ages. Still, one day not too long ago I was standing in a new business that wasn’t on maps yet. I added the business, photos, hours, even their phone number and it was immediately rejected.

Sometimes you can get small changes approved but change more than one or two things and it’s immediately rejected too. Doesn’t help much with saying “road isn’t here” though.
