Diverging Diamond Interchange Survey

Diverging Diamond Interchange

1. Introduction – Interstate 44 and Missouri Route 13 Diverging Diamond Interchange (DDI)

We appreciate your time and interest in sharing your opinion. This information is being collected and summarized for inclusion into a report on the First Diverging Diamond Interchange (DDI) construction in North America. We are an independent firm who has been hired to collect and summarize information on the traffic operations and safety of this DDI. This study will assist in future transportation decisions made in Missouri and across our country regarding how applicable the DDI transportation solution is for other planned transportation improvements. Our only interest in this survey is to gain accurate information on what you think of the DDI, so please respond as accurately and completely as possible – your opinion is important.

We would encourage you to return and take the survey again, if while traveling through the interchange you notice something different that would change your opinion on the operation and safety of the interchange.
