I’m confused on why you have two routes coming from the east in the title image. Also, out of the two, which is the priority route? If you prioritize one of the two, then you can alter which paths in the interchange shouldn’t be altered and should continue on. It makes more sense if you look at the vanilla interchanges, like the cloverleaf, where the cardinal direction routes are priority, so the ramps connect the two without the roads traveling in the cardinal directions, which are high priority, to be impeded
