Never seen a SPUI shifted like that. I wonder where else you can find one.

There is a similar SPUI at Interdtate 225 and Alameda Avenue in Aurora, Colorado.

As well as another one at St.Paul, Minnesota at I-694/Rice St. where a former diamond interchange was converted into a SPUI.

Of courses there's one in LA as well.
