I just learned on the local news yesterday that a new SPUI interchange is coming to the Kalamazoo (MI) area at the junction of U.S. 131 and Stadium Drive (BL I-94). I don't know what others think of SPUI's, but I rather like them. This is cool!

It's an appropriate location for one. The current cloverleaf interchange is rather dangerous with the high traffic volumes both on Stadium Dr and US-131.
