Interchanges with ramps in two states

[Dunkelheit]

Off the top of my head, I can think of three, all within Kansas City:

The I-435/State Line Rd. interchange is divided neatly in two, half in Missouri and half in Kansas.

The I-35/Cambridge Circle interchange has a small chunk in Missouri, with the rest in Kansas.

The I-670/Genesee Street/Wyoming Street interchange lies mostly in Missouri, with a small piece in Kansas.
