Not my experience. I'm in the USA, and there are still bank branches everywhere, I'd say as many as ever and new ones are being built. In fact within a mile of my house the finishing touches on the latest new one (full remodel of a former restaurant building) are just about done.

That's an amazing difference compared to the UK. My local town had 5 bank branches ten years ago, now there are none. Until 2 weeks ago we didn't even have a cash machine; fortunately there is one now. It is something that has rapidly changed in the last 15 years.
