This past weekend I was driving in the Burlington, WI area and noticed signage off of WI 36 for a "Business 36" (the usual WI 36 shield with a Business banner), so I followed it. The route begins at the 36/11 intersection south of the city and follows State Street and Milwaukee Avenue to the 36/83 bypass section north of the city (presumably the old 36 routing before the 36/83/11 bypass was built?). The route is well-signed with frequent reassurance shields and clear directional signage at major interchanges. It seems to meet the criteria for inclusion.
