I was in Catoosa earlier, and about 1/2 mile or a little further south of the US 412 overpass there is a sign that says "End Will Rogers Turnpike Maintenence" and another sign that says "Begin Creek Turnpike Maintenence" (I am paraphrasing.) The pavement also changes at this point. So despite what some have said that the Creek begins where the old Will Rogers was cut off, the Creek Turnpike doesn't make it to I-44/US 412.
Looks like WILL ROGERS TURNPIKE MAINTENANCE ENDS / CREEK TURNPIKE MAINTENANCE BEGINS: http://maps.google.com/maps?hl=en&ll=36.151685,-95.732363&spn=0.007935,0.016512&gl=us&t=k&z=17&layer=c&cbll=36.151958,-95.732359&panoid=8gSQS9BBw3FirLag1eCgyg&cbp=12,222.68,,0,6.2
But there's Creek Turnpike reassurance before that point: http://maps.google.com/maps?hl=en&ll=36.156848,-95.732331&spn=0.007935,0.016512&gl=us&t=k&z=17&layer=c&cbll=36.156513,-95.732328&panoid=loQn2zXMBGL4DGdpGFwjDQ&cbp=12,193.27,,0,3.33
You might be an anal road enthusiast if you think the Will Rogers Turnpike ends at the maintenance change.
Well, the pavement changes so that's enough evidence for me.
If they were maintained by different agencies I'd say you have a point, but they're both ultimately maintained by OTA. This is just which division is responsible for maintaining which segment of road (and the breakpoint is probably placed there so the 44/412 interchange falls entirely in one division, not half and half).
