The Wisconsin Highway 130 crossing of the Wisconsin River has long linked communities in Iowa, Sauk, and Richland Counties in Wisconsin. When three historic steel truss bridges built in the 1930s and 1940s could no longer meet the region’s transportation needs, the Wisconsin Department of Transportation (WisDOT) launched a plan to deliver a safer, more reliable route while protecting the river’s sensitive ecology.
WisDOT retained our team to develop and oversee a plan to protect the environment during bridge removal and replacement. For 13 years, we provided environmental services from planning through ecosystem restoration.
Our team conducted wetland delineations, rare species surveys, and a freshwater mussel relocation of nearly 1,800 mussels representing 21 species—including state- and federally-listed threatened and endangered species—to protected habitats. We also designed underwater structures to support mussel populations and developed a floodplain restoration plan, which we implemented to return the former roadway to thriving wetland.
Completed ahead of schedule, the new bridges combine modern engineering with environmental stewardship and nature-based solutions. They reconnect communities, improve safety, and protect the Lower Wisconsin State Riverway’s rich biodiversity.
