This is the location in question:

In this example, I could just block the turns on the small connecting road section. But if there were parking lot roads (or actual side streets) at that intersection, that would potentially block the allowed turns.

I changed my intersection to this option I like the look over the bow tie. I tried to do like this at first but had problems getting the roads to stack. After reading your post I tried again and figured it out not to hard if you draw the second street out to give you a triangle while you adjust turn restrictions then up it's level and drop it over the original street.

"The triangle of no U-Turn"
Not only does it use 1 segment less than the original, it also works with only 3 turnrestrictions. All routinginstructions as expected and no hidden segments.
