Click HERE for an in-depth document on the Diverging Diamond Interchange.


A Diverging Diamond Interchange (DDI) is a type of interchange designed to increase capacity, decrease congestion, and minimize new construction cost.

A DDI is different from traditional interchanges that you would typically encounter when entering or exiting an interstate freeway.  They allow for free left turn movements, meaning that left turning vehicles will not cross in front of opposing traffic.  By eliminating this movement, green time can be increased at traffic signals resulting in improved intersection capacity and safety.

MDOT has conducted a survey which concluded that the 96.7% of those who participated preferred to close the existing bridge during construction.  This will decrease construction time up 10 weeks and costs of approximately $500,000.

Construction will begin in spring of 2015 and is expected to open to traffic in fall of 2015.
