MnDOT will be constructing Diverging Diamond Interchanges (DDI) throughout the state. They:

• Cut overall traffic delays up to 60 percent
• Improve safety by eliminating standard intersection geometrics and conflict points
• Provide better traffic operations and show some excess capacity 20 years into the future
  • Elk Run Diverging Diamond
  • St. Cloud/Sartell Diverging Diamond

 

 

Driving a DDI

Traffic crisscrosses at either end of the bridge, so instead of making hard left turns, drivers veer to the left for access.

 

Pedestrians will cross to the middle of the bridge and walk in the middle between the eastbound and westbound lanes with protective barriers on either side.
