Background/Context

WisDOT needed a solution to improve safety and operations at this rural intersection.

Results

While with WisDOT, MTJ Roundabout Engineering’s Mark T. Johnson provided the capacity analysis and final horizontal geometrics. He also played a key role in the public outreach effort.

This high-speed approach design includes elements that provide optimal safety and operations specifically for higher speed environments and contexts.

The roundabout opened in 2003.
