I-90 Wisconsin Dells | Wisconsin Department of Transportation

Knight provided the preliminary and final design of the asphalt shoulder rehabilitation of I-90 in Sauk and Columbia Counties, Wisconsin. The existing shoulders were milled and repaved while maintaining two-lane traffic during daylight hours. Knight performed Length of Need assessments and upgraded all beam guard end treatments to Energy Absorbing Terminals. New signage was also incorporated into the project. The project was developed on an expedited schedule due to the severe deterioration of the shoulders.
