Split intersection

A Split Intersection is a rarely built at-grade variant of the diamond interchange. Compared to a conventional four leg intersection or road crossing, the artierial road is being split-up into separated carriageways by 200 to 300 feet, allowing a queue of left turning vehicles behind a completed turn into the crossroad without any conflict to oncoming traffic. On the crossroad, the four leg intersection is being replaced by two intersections. The beginning one-way traffic at the fourth leg makes the intersecions reduce the number of conflicts similar to a three leg T-intersection to improve traffic flow.
