That big and you failed to see the pothole?

However, as above get quotes and try a claim.
Also keep and eye on the hole and see how long, if at, all they take to fill it in.

Good ammunition for your claim if they don't fill it in as they may already have known about it.
Looks like lots of work going on in the area, maybe it's scheduled for a resuface soon and they are holding off filling it.
