STH 29 from CTH O to STH 107 - Marathon County, Wisconsin

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.
