Look closely at the map on that page. It shows interstate 41, and U.S. highways 60 and 83.
In Hartford, Wisconsin, there is no interstate 41, and there are no U.S. highways 60 or 83. There are, however, U.S. highway 41 and state roads 60 and 83.
Probably a nice place to eat, if you can figure out how to get there!
