Even though the Kickapoo exit number scheme is explained as a "count-back" from I-44 exit #149, it's also approximately the mileage from a given point on the turnpike to the TX state line at the Red River -- not that anyone thinks that this facility will reach that far south! But earlier speculation about a diagonal shunt over to I-35, if ever implemented, might actually be a close approximation of I-35 aggregate mileage as diverted to the Kickapoo. That leads to a 2nd thought: the exit numbers may well change once the pike is signed as part of I-240, so the existing scheme, regardless of rationale, is serving as a temporary "placeholder". Do any OK posters have a rough idea regarding when I-240 signage will be applied?
