Improving interchange safety
MnDOT is constructing Diverging Diamond Interchanges throughout the state. These interchanges:
- 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
