Westbound 44/412 west of the Cherokee casino... there is an annoying curve (which I thought they were going to remove with all the construction they've been doing out there)....  
Just as the curve starts there is a "Tulsa" sign with an arrow over the left lane of traffic..
I have no idea why that sign is there.   But, everyone not familar with the stupid sign merges over to the left lane (obviously the right lane must lead anywhere but Tulsa... might as well barrel off the right lane).
 Does the right lane end?  No
 Is the right lane exit-only?  No
 Is there any exit?  No  (the sign is just past the 66 exit)
 Is there any sort of split?  No
Perhaps a standard on the side of the road:  Tulsa x miles... is their intention?

I'm just guessing, but maybe that sign was in place when that was the 44/66/412 interchange, before they built the Creek to Will Rogers interchange, and previous to that there were two signs, one sign on the left of 412 for the 44/66/412 West and one on the right for 44/66 East  since that was the way to get to the Will Rogers and to 66.

Before the Creek Interchange you would have seen something similar to this on the 412, minus the Creek Tpk sign.



The abandoned stretch of the Will Rogers is where the original toll booths were so heading east it split to 33/412, 44, and 66.
