WIS 73 (Neshkoro to Wautoma)

design

We are proposing to improve 7.1 miles of WIS 73 from the White River Bridge in the village of Neshkoro to WIS 21 near the city of Wautoma. The purpose of the project is to improve the existing asphalt pavement to extend the life of the pavement. The pavement is showing signs of distress including longitudinal and transverse cracking as well as alligator cracking. These cracks allow water to enter the pavement structure and accelerates the pavement deterioration and increase maintenance costs and intervals. The County YY intersection has also been identified as having crash trends. Proposed improvements include: Removing and replacing 1-2 inches of the existing asphalt2-inch mill and overlay from the White River Bridge to Bluff Street in the village of Neshkoro and from County F to WIS 21.1-inch mill and 2-inch overlay from Bluff Street to County F.Modifying the County YY intersection to address safety concernsReplacing one deteriorated culvert under WIS 73 near Silver LakeUpgrading curb ramps in the village of Neshkoro to meet current standardsAddressing some drainage concerns in the NW quadrant of the White River Bridge in NeshkoroReplacement of sideroad culvert at Cottonville Drive County YY Improvements: The County YY intersection has a history of crashes involving westbound vehicles on County YY failing to yield to southbound vehicles on WIS 73. To address the identified crash pattern, a minor realignment of County YY on the east leg was selected as the preferred alternative for the intersection improvements as it addresses the crash pattern with low impacts and cost. This solution will realign the east leg of County YY to reduce the skew angle of the intersection improving sight lines for vehicles at the intersection.
