Have you tried reporting it? My parents recently moved into a new house built one year prior and I reported it a few days after they moved in. It took about 9 months, but they finally added the road in and populated ALL the addresses on the street, not just the one I reported. Google maps still does not have the roads or street numbers listed. Just wanted to throw that out there.

Edit: Also want to add that it has been two years since my parents moved in. Went in to Waze Map Editor and added the road myself, so their turnaround time was instant. Apple Maps took 9 months, like I said, but Google Maps still has no info on the street despite having all the houses in clear satellite view.
