I live in the Kansas City area, so I drive this road all the time. L P Cookingham Dr is a fully access controlled freeway with interchanges at I-29 (east end), Canberra Street, Bern Street, and Paris Street. Canberra Street, Bern Street, and Paris Street are all within the airport property (serving parking, rental cars, etc.), but these are true interchanges, not at-grade connections. At the west end, there are free-flow connections into the airport terminals (under reconstruction at the moment since a new terminal is being built). This freeway is also called Missouri Route D, but that is not signed and it may only be a state route from I-29 until it reaches the airport boundary. I think you have a simple choice here -- you either include freeway connections from an Interstate highway to an adjacent airport or you don't. But please be consistent.
