This morning on one of the local radio stations, a spokesman from the KTC was called to discuss problems that some motorists were having with the new I-69 signage. At the newly opened interchange where I-69 ties together with the Pennyrile Parkway and Western Kentucky Parkway, the new signage shows Fulton, KY as the new control city. Apparently some drivers who were used to seeing Paducah, KY were getting confused as to which road they should be on and were making U-turns trying to get themselves on the correct roads. The KTC spokesman explained to the listening audience that the new I-69 would now be using Fulton as its new southernmost control city since it's on the border with Tennessee. He also stated that the various GPS devices should be getting software updates with the new routing and exit mile markers within the next few months. I found this rather amusing, since I had recently driven this newly rebranded section of I-69 and found the signage nowhere near complete. What was even more amusing was this spokesman stated his confusion why in Indiana, when one drives northbound into Evansville on US 41, the US 41 control city is shown as Vincennes, IN. I guess that he didn't understand that drivers reading that sign were already in Evansville, so it makes no sense to list a control city as the same one that you are presently in.
What I find interesting is that the KTC is already signing Fulton as its new control city, yet I-69 "officially" does not go all the way to Fulton. Based on what I've been able to research, I couldn't find information confirming that AASHTO/FHWA gave approval to KTC to re-sign the Purchase Parkway as I-69. I wonder why the KTC is doing this? Presently, in southern Indiana, none of the I-69 North signs show any control city. INDOT cannot have these shown as "Indianapolis" because, technically, I-69 does not go all the way to Indianapolis. Interesting decision by the KTC.
I also don't see why the KTC couldn't have left Paducah as a control city, since technically I-69 and I-24 share a common alignment. I'd be curious to read others' thoughts on this. I note this because, in Illinois, I-57 South shows Memphis, TN as its southernmost control city (even though I-57 terminates into I-55 and doesn't go directly to Memphis).
