- It is a concave non-stop interchange with left and right turn only lanes merge with the main road.

- It is a two-level interchange with possible left and right turns without signals, while it takes up the minimum amount of area for non-stop interchange.

- Off ramps are to the right side of the main road, then splits off again to left and right. Vehicles then merge onto the main roads of their destination. This is identical to the flow of traffic into an intersection.

- There is no intersecting point of conflict, and there are only split offs and merges within the intersection.

- Since roads merge after they split off to the right from the main road, there is no point of conflict as seen in the cloverleaf interchange.

- Since the required area is similar to the conventional intersection, it can be applied in arterial roads in urban areas, where off ramps are to the right and space is restricted.

- Most of the non-stop interchanges in use today are concave to the opposite side of the main road where it splits off for left and right turns.

- This type of interchange requires a significantly large area. (Refer to photograph on right.) Such non-stop interchange cannot easily be used in metropolitan areas due to the space it requires.

- Furthermore, points of conflict between vehicles intending to take the off ramps and merging vehicles pose threats of accident.

- Increasing the conflict area to reduce the possibility of accidents is one of the reasons the interchange requires larger area.
