Diverging Diamond Interchange: Performance Evaluation (I-44 and Route 13)

Performance evaluation was conducted on the first “diverging diamond interchange (DDI)” or “double crossover interchange (DCD)” constructed in the United States. It connects Interstate 44 and Missouri Route 13. This evaluation assessed traffic operations, safety, and public perceptions to determine the changes between the previous standard diamond interchange and the new DDI/DCD.
