You also have to turn the "Globe" off each time you open Google Maps in a new browser instance.
If you log in to a Google account, it should save it the first time you do it. Mine automatically disables Globe mode every time.
I just went to the Midtown Tunnel and MLK Freeway, and it was under construction when I opened it, and I had to turn the "Globe" off to see it completed.
Same with Dominion Blvd as well, the imagery still shows when they re-routed traffic on VA-166 so they could construct the new bridge approach and the VA-166 interchange. It's nice to see the older imagery, but if I wanted old imagery, I'd go to Google Earth or Historical Aerials. Meanwhile, with Globe mode disabled, the imagery was updated in April 2018, and the entire project is shown completed. Same with the Midtown Tunnel & MLK Freeway.
Globe mode is just something Google likes to shove in people's face, and quite frankly, a lot of people are frustrated by it.
