Is Anyone Else Curious About The Arrow On The Bottom Right?

Sure, the whole sign is super confusing, but what is that bottom right arrow doing? Is that a road that connects to the main road, or just an arrow that tells you where you are on the sign? We are entirely puzzled. It is like someone took a regular road sign and added a ton more routes to it. Guess we will be driving home again because we do not want to deal with this mess. Still very funny, though. Maybe it is a prank.
