Wow, this is a really tricky intersection! I looked over it and see no problems. (At first I thought I had a better way, got halfway through trying it, and changed my mind, haha). The only minor issue is that someone turning right off of Parker Rd will have to do a crazy backwards-right-turn according to the map. But as I understand it, most routing software will look at the overall shape (and roads nearby) to figure out what's really going on. Anyway maybe another more experienced mapper can chime in if they have a better way to do this!
Also nice job on the lane tags. :)
