It's not super unusual for the area around the Grand Old Opry (old Opryland) to flood. I remember floods in that area in the 60's and 70's. I'm sure others remember pictures of Rudy's buffalo stranded on a low hill. I do find it unusal for downtown to flood though. Yes, it is a mess. 24 and 40 have both been closed in some places, although I think they are both open now.
