This roundabout project is located at the intersection of USH 10 and STH 32/57 in the Town of Brillion. The intersection had safety issues with trucks on USH 10 frequently going through on red lights even with the yellow timing maximized. The accident rate for crashes over the past five years was 0.45 with seven out of nine resulting in injuries.
The new single-lane roundabout is designed with splitter islands to help reduce the speeds as traffic approaches the intersection. The roundabout is also designed to facilitate large farming equipment and oversized trucks. Due to many drainage issues located around the intersection, a hydraulic analysis of the area was performed. The new culverts and ditches will significantly improve drainage in the area.
