Hwy 63 and Co. Rd. 112 — Olmsted County
Visit the Hwy 63 and Co. Rd. 112 construction website to see the most recent updates. This public engagement website shares the planning background.
Construction is scheduled to begin June 2, 2025 and it is expected to be completed by September.
We are building a roundabout at the intersection of Hwy 63 (75th Street Northwest) and Olmsted Co. Rd. 112 to reduce crashes and improve driver safety in the area. This is an intersection with two highway-speed roadways. Stop signs control traffic on Co. Rd. 112. At times, drivers become impatient because of limited gaps in traffic. This has led to a sustained history of crashes.
Building a roundabout at the intersection will help reduce dangerous driving behavior and the number of crashes by improving traffic flow.
Benefits of a roundabout
- Significantly reduces the risk of serious and fatal crashes
- Roundabouts show an 86% decrease in fatal crashes and an 83% decrease in life-altering injury crashes
- Allows drivers to get through the intersection more safely and in less time
- Roundabouts handle high levels of traffic with less delay than most stop signs or signals
- Slows traffic to make entering and exiting the area easier for all users

In partnership, Olmsted County and MnDOT are planning to build a roundabout at the intersection of Hwy 63 and Olmsted Co. Rd. 112, near Rochester. Construction is expected to occur in 2025. High speeds and large volumes of traffic near the intersection make it difficult to safely drive through the intersection resulting in impatient driving behavior and a sustained history of serious accidents.

Benefits of a roundabout:
- Improve safety and reduce the risk of serious and fatal crashes
- A MnDOT study demonstrated roundabouts may reduce fatal and serious crashes by more than 80%
- Reduce impatient driving behavior
- Slows traffic to make entering and exiting the intersection safer and easier for all users
- Allow drivers to travel through the intersection more efficiently
- Dangerous collisions are less likely by reducing speeds and eliminating left-turn and crossing accidents
Navigating a roundabout
Roundabouts may be unfamiliar at first, but with practice navigating them will get easier with each trip. Watch our roundabout simulation and see how it works. (Click on the expand icon in the lower right to enlarge the video.)
