I don't see any reason to not do a simple u-turn lane for this one. (Unless of course the AM's and CM's have a problem with it). The only thing I would suggest is, despite the real world u-turn lane starting back near the prior intersection, keep the u-turn lane's length to a minimum so that it doesn't confuse things visually.
Not only does this function as a u-turn, but is also visually says "hey I'm a u-turn" for anyone who is not routed through the turn.
