I drive through that interchange several times per year following the Pennyrile Parkway. It is currently a traditional cloverleaf interchange, having been opened in late 1963. At this time it seems adequate to handle current traffic demand without any trouble.
I have no way to know what KYTC will end up doing, but it is my suspicion that the loop that serves the eastbound to northbound movement will be replaced with a direct flyover ramp. The current ramp that serves the soutbound to westbound movement may end up being widened but otherwise keep its same alignment. Other than that I figure the rest of the interchange will remain as it is.
