What shield is missing (I-44 @ US 169 in Tulsa)

It appears that this sign was directly copied from an older sign that had 3 route markers. What was the other marker for? OK 33?

That would be my guess

Could be shitty Oklahoma sign formatting.

You are correct.  They used to show I-44, US66, and OK33.

Here is a sign with a broken panel with the gap between the shields:

https://maps.google.com/maps?ll=36.142859,-95.860297&spn=0.001409,0.002406&t=k&layer=c&cbll=36.142948,-95.8603&panoid=W2OHbfETTYi-_Uyq258Dqw&cbp=12,178.03,,0,4.92&z=19

That interchange is interesting. There is no longer a movement from EB I-44 to SB US 169. There is a funny little ramp that connects to 15th Street. Also, on the merge from the SB 169-WB 44 ramp, the yield sign faces the lane to the left (the C/D lane). The C/D lane has to stop and the yielding traffic doesn't. This could be a relic from when this stretch of I-44 truly was US 169.
