Working list – Diverging diamond interchanges in the USA

A working list of diverging diamond interchanges (DDIs) is listed in alphabetical order by full state name under each calendar year. The first DDI in the United States opened in 2009. This style of interchange design cuts down the number of potential conflict points for traffic and allows it to flow more smoothly, while reducing the number and severity of accidents.

As is clear from the list, the state of Missouri was an early leader in the development of DDIs. Today, most states have constructed at least one diverging diamond interchange. Any additions, corrections, or suggestions to this list are most welcome.
