So, there is going to be an interchange with I-69, I-169, and I-569 converging? Sounds like overkill to me.
I do agree with some of our members posting that I-71 would be a good extension over the WK and Pennyrile Parkways, as long as a possible Interstate designation is one number. Plus, there would be an I-69/I-71 "bump"! Or, for those who feel that this is a more east-west routing, I-52, I-54, I-56, or I-58.
As far as making "every" divided Kentucky Parkway an Interstate highway--no. I do agree with I-165 applied to the Green River, sorry, Natcher Parkway. The Cumberland Parkway would be a good candidate for an I-365 or I-765 number (I know, I-565 could be used instead of I-765, however, I like the descending numbers in this case). The others do not, in reality, need an Interstate designation (unless, as I mentioned above, one number could be used for the WK and Pennyrile). Some improvements with the "old" toll interchanges would have to be done before these Parkways could even be considered to have an Interstate number applied.
Most drivers know them by their Parkway names--or used to, before many of them have had Commonwealth political leaders' names attached to them. It basically is just a push to have the advertising of an Interstate logo on a highway near these towns along the Parkways.
