Superstreet Diagram (IMAGE)
Caption
Superstreets are thoroughfares where the left-hand turns from side streets are re-routed, as is traffic from side streets that needs to cross the thoroughfare. In both instances, drivers are first required to make a right turn and then make a U-turn around a broad median. This diagram shows superstreet traffic patterns. The lefthand image is of the most common superstreet design, in which traffic on the superstreet itself can turn left. In the righthand image, traffic on the superstreet cannot turn left.
