i figured if they were going to reconfigure the road course, turn 7 (the turn onto Hullman) would be made into a left and the road course would exit in a right turn into the north chute. Traffic would then go through oval-turn 3 "backwards" and road course turns 11 & 12 would become part of a chicane before traffic returns to the previous route. i don't feel like drawing a map right now.

Yes i know Hullman leads to a tunnel, but if a strong enough retaining wall were built, traffic could run parallel.

I don't feel like drawing a picture.
