A Diverging Diamond Interchange (DDI) is based on a standard diamond interchange common in Arizona, but with one major difference —traffic shifts briefly on the left side of the road between highway ramps, allowing left turns without crossing oncoming traffic. The freeway will feature two half-DDIs in the Pecos Segment, as there are no connection points to the south. Features of a DDI:
- Innovative, proven solution for increased safety and mobility
- Able to move increased traffic more quickly and safely than traditional intersections
- Minimizes right of way footprint over some other types of interchanges
