Summary of Work

  • For more information on how these intersections work, see below or visit our webpage on RCIs.

Traffic impacts

  • Lane closures and lane shifts
  • Project will be done under traffic and motorists will shift to single lane in each direction.
  • Hwy 32 will be detoured during the construction of the RCI. Detour map coming soon.

Reduced Conflict Intersections

Reduced Conflict Intersections decrease fatalities and injuries caused by T-bone crashes on four-lane divided highways. In some parts of the country RCIs are sometimes referred to as J-turns, R-CUTs, Michigan Lefts.


  • RCI's improve safety, with up to a 70 percent reduction in injury crashes nationwide
  • Currently there are over 30 RCI’s in the state
    • They’ve been built on some of the state’s most dangerous intersections
    • There have been no fatal or severe injury crashes at any of them
  • Minnesota’s first RCI was built on Hwy 71 in Willmar in 2010
    • Prior to construction the intersection averaged 9 crashes per year
    • In the 10 years since, there have been only 3 total (none were severe/fatal)

How do they work?

While on Hwy 2

  1. Right turn onto Hwy 32: no change, right hand turns can be made the same as before
  2. Left turn onto Hwy 32: no change, use left turn lane
  3. Cross intersection (to remain on Hwy 2): no change

While on Hwy 32

  1. Right turn onto Hwy 2: no change
  2. Left turn onto Hwy 2: turn right onto Hwy 2, make a u-turn
  3. Cross intersection (to remain on Hwy 32): turn right onto Hwy 2, make a u-turn, turn right onto Hwy 32

Why do they work?

Understanding Reduced Conflict Intersections

With an RCI, drivers from the side street only have to be concerned with one direction of traffic on the highway at a time. You don’t need to wait for a gap in both directions to cross a major road. Traditional four-lane divided highway intersections have an elevated risk of severe right-angle crashes (commonly called “T-bone” crashes), especially for drivers attempting to cross all four lanes of traffic or turn left. At a traditional intersection, motorists from the side street need to look in both directions to cross a four-lane divided highway. Left turns require the same level of attention.
