9 lane intersections are extremely common in Phoenix. 3 lanes in each direction, 2 lanes for a left turn, and 1 lane for a right turn. Often times there will be a small median where one could wait out a light, but not always. Scottsdale @ McDowell[1] is an example of one without. If you pan around to any of the major intersections (every 1.25 miles in each direction, generally), they are pretty much all this large.
