caption_attribution_description: English: Markers for Interstate Highways 41, 43, and 894 south of Milwaukee, Wisconsin. This is one of two instances of a wrong-way concurrency in the United States involving two Interstate Highways. It is also one of only two places in the United Sates where three Interstate Highways share the same roadway.
context_page_description: Interstate 41 is a 176.33-mile-long north–south Interstate Highway connecting the interchange of I-94 and U.S. Route 41, located 0.9 miles south of the Wisconsin–Illinois border at the end of the Tri-State Tollway in metropolitan Chicago, to an interchange with I-43 in metropolitan Green Bay, Wisconsin. The designation travels concurrently with US 41, I-894, US 45, I-43, and sections of I-94 in Wisconsin and Illinois. The route was officially added to the Interstate Highway System on April 7, 2015, and connects Milwaukee and Green Bay with the Fox Cities.
context_section_description: I-41 begins at the I-94/US 41 interchange in Russell, Illinois, located 0.9 miles (1.4 km) south of the Wisconsin–Illinois border at the end of the Tri-State Tollway. The highway continues north concurrently with I-94 to the Mitchell Interchange in Milwaukee, turns west to run concurrently with I-894 and I-43 to the Hale Interchange (forming a brief wrong-way concurrency with I-43), and turns north to run concurrently with I-894 and US 45 to the Zoo Interchange, with the US 45 concurrency continuing until the I-41/US 41/US 45 split near Richfield. The Interstate roughly parallels I-43, which runs north–south along Lake Michigan from Milwaukee to Green Bay. I-41 runs through the Fox Valley (including the cities of Fond du Lac, Oshkosh and Appleton, along with the Fox Cities) and Green Bay, where it ends at the I-43 interchange. The Interstate is approximately 176 miles (283 km) long and located almost entirely within the state of Wisconsin, and is completely concurrent with a slightly adjusted alignment of US 41 to its termination in Green Bay.
