Now check out the ParClo B4 near Sims. Do you think that interchange is overbuilt?
Why are you always worried about interchanges being overbuilt? Partial Cloverleafs are literally just cloverleafs with even fewer ramps. Apart from the land they can take (less for partial variations, mind you), cloverleafs are considered very unobtrusive, as they require only a single overpass or underpass, and are only two levels. That interchange near Sims would qualify as overbuilt, IMO, if there were multiple left turn lanes, traffic signals, maybe even a flyover...but what's there now is far from overbuilt.
