STH 124 & CTH S

Chippewa Falls, WI


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


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.
