Interstate 41 runs 174 miles entirely within Wisconsin, from the Illinois state line south of Kenosha north to Green Bay. It shares the lakefront with I-94 past Racine and Milwaukee, then turns inland and runs the length of the Fox Valley through Fond du Lac, Oshkosh, Neenah, Appleton and De Pere. It is the newest number on a Wisconsin shield: posted in 2015 along a route that had been US 41 for decades, which is what a good many local directions still call it.

Mile markers count from each state's southern line and start again at the next one, which is how most states number their exits as well. They are measured along the same road geometry these pages draw, so they land within a mile or two of the posted markers. A toll road that runs its own continuous numbering is the exception — on the New York Thruway the posts continue from New York City — and there the figure is how far into the state the place is rather than the number on the sign. Distances are measured state by state, never across a gap.
