DDI Design Plans
Mike McKee, Horrocks
10
DDI benefits
State and national data clearly show that the DDI design improves safety.
Left-turning traffic uses a “crossover” lane instead of waiting for oncoming traffic to stop.
The design reduces the number of potential conflict points (a traditional diamond interchanges has 26, while a DDI has 14).
The DDI design reduces the opportunities for head-on collisions.

Exit 332 - Final Design Plan

Exit 333 - Final Design Plan

The DDIs in Rexburg will:
Reduce congestion
Improve safety and reduce injuries
Move high volumes of left-turning traffic
Not require the interchange structures to be rebuilt, reducing costs

Questions/Q&A
What questions do you have about the Diverging Diamond Interchange (DDI) design?
What would be the best way to educate the Rexburg community about the DDIs and how to drive them?
17
Construction Plans
Mike McKee, Horrocks
18
Anticipated schedule
ITD anticipates construction will occur in summer 2024.
19
Anticipated construction
Each interchange will be fully closed, one at a time
Each closure will last for approximately 6 weeks
One interchange will remain open as a detour route
US-20 will remain open during construction
20
Schedule benefits
Crews will be able to complete both interchanges in one construction season.
ITD will be able to construct the University Blvd. (exit 332) interchange while Madison High School is out for summer break and when BYU-Idaho will be least impacted.
Full closures will allow crews more room to work, improving safety.
The time period of traffic impacts to drivers is shortened.

Do you have any suggestions on how ITD can best inform the community about construction?
