Interesting... I'm not extremely familiar with Fayetteville traffic, but I do know the Jughandle is used by right-turners from College to Joyce. Nice idea, but it's not working as it should

. My friend's sister actually got in a bad accident there, because she thought the jughandle was a shortcut to College, from Joyce. It was her own stupidity, but it goes to show that driver familiarity is an important thing to consider, and signage be more than adequate. You can't stick something that isn't familiar, and expect drivers to figure it out, without adequate signage... and the signage for the jughandle is not adequate.
This mess at College & Joyce sounds like one that they are working on in Sioux Falls, SD. Here's a link for the planning: http://www.sddot.com/PE/projdev/planning_ss_I29Exit77.asp
The 41st & Louise there is comparable to the College & Joyce intersection... The center turn overpass is interesting... and could fix College & Joyce... Sounds pretty expensive though.
