New interchange increases safety, improves habitat
State Highway 29 is one of the most important and highly traveled east-west roadways of the Wisconsin highway system. The Wisconsin Department of Transportation was planning a roadway safety improvement project to support its conversion to freeway standards. Our team completed a design-intensive process to mitigate potential environmental impacts and improve the natural environment. The new diamond interchange fits within existing roadway constraints while minimizing environmental impacts.
After completing an interchange location study and incorporating feedback gained through public involvement, our team prepared design plans and completed environmental analysis. Our scientists and engineers applied integrated design techniques, collaborating with WisDOT and the WDNR to improve fish habitat, wetlands and floodplains. By incorporating environmental factors into the design, we delivered a safe roadway that successfully reversed decades of environmental degradation, providing local habitats with an opportunity to return to their natural states.

From the Client
Taking into consideration both the safety and environmental factors, Mead & Hunt was able to provide a safer and more environmentally-friendly roadway for travelers. The team was able to improve environmental conditions within the interchange area by restoring fish spawning areas that have not been active since the 1990s.
