USH 10 & STH 55 Intersection

Calumet County, Wisconsin

 

This project is located at the intersection of USH 10 and STH 55, southeast of the City of Appleton in the Town of Harrison, Calumet County. The existing condition required STH 55 traffic to stop for USH 10. Although the intersection had good sight distance in all directions, drivers were still making poor decisions when leaving the stop sign. The intersection had a crash rate of 1.55 with over 80% of the crashes being right-angle crashes and 62% of the crashes resulting in either injuries or fatalities.

The roundabout is a single lane rural roundabout. Because of the high speed approaches, the splitter islands were designed to help reduce the speeds as traffic approaches the intersection. The roundabout was designed to facilitate large farming equipment and oversized trucks.
