Hwy 44 and Hwy 76 roundabout – Caledonia

This survey closed July 7th, 2024.

Thank you to everyone who provided their feedback. A summary of what we heard is available for review.

In partnership with the City of Caledonia, MnDOT plans to build a roundabout at the intersection of Hwy 44 and Hwy 76. Construction is expected to occur in 2028.

From Jan. 1, 2014 to Dec. 31, 2023 there were 17 recorded crashes. 11 of the 17 were right-angle, also known as T-bone, crashes. The goal is to reduce the number of right-angle crashes which are most likely to be life-altering or deadly.

With the support of the City of Caledonia, MnDOT applied for Highway Safety Improvement Program (HSIP) funds. As part of the process, a MnDOT team gathered crash statistics and determined the likely causes. They then took a deep look at potential solutions, including a traffic signal, J-turn and other options.

A roundabout was found to be the best solution to reduce severe crashes at this site.

Conflict points and collision angle

A conflict points is any location where the path of roadway users intersect. They are categorized as crossing, merging, or diverging. A typical intersection has 32 conflict points. 16 of them are crossing which can result in right-angle crashes. 

A roundabout has 8 conflict points. 0 are crossing. While there may be crashes, this would greatly reduce the severity.

Speed

Speed also contributes to the severity of crashes. As speed increases, the amount of energy that can be transferred in a collision increases exponentially. This contributes to the severity of crashes at the intersection. 

By design, vehicles must slow before entering a roundabout. If there is a crash, this would help reduce the severity. Additionally, this would also help slow vehicles as they enter the City of Caledonia.

Share your feedback:

MnDOT and the City of Caledonia applied and received HSIP funds to construct a roundabout. Community feedback will help us develop specific features of this roundabout. Please participate in this survey to help us identify community concerns and needs.

The community will have more opportunities to review the design and provide feedback before construction.
