What are the benefits of converting the existing interchange to a diverging diamond interchange?

Diverging diamond interchanges work well in areas of heavy traffic. Approximately 23,000 vehicles per day travel through the interchange. A major benefit of the DDI design is it allows motorists to make left turns without crossing in front of oncoming traffic. It will also improve traffic flow onto and off of the interstate ramps.
