I sincerely doubt that the MoPac/183 interchange is more than 1 or 2
square miles.  I hope the "20 square miles" remark was simply a typo
and not some confusion about how much land is "20 square miles".

The usual reasons for large interchanges is making the curves gentle
enough that the speed through the interchange doesn't change that
much.  If you force the driver to stop (the most drastic step) in
order to conserve space (a nice 4 way stop sign comes to mind ...),
the result will be increased traffic congestion.  Allowing traffic
to flow at a constant speed provides the least congestion (and the
accompanying noise and pollution).
