What is a DDI?

A Diverging Diamond Interchange (DDI) crosses traffic to the opposite side of the road across an interchange so vehicles have unimpeded movements onto the freeway ramps. Left-turn movements, which are a typical challenge with standard four-way interchanges, are eliminated with a DDI.
