Wis. Stat. § 84.104
In order to commemorate the 32nd Infantry Division, also known as The Red Arrow Division, which, while composed mainly of men from Wisconsin, Illinois and Michigan, brought fame and glory to these states during World Wars I and II by their sacrifice, devotion and bravery and which is now established as a Wisconsin national guard division, the department is directed to establish a highway memorial designated route 32 by renumbering certain existing highways linking Illinois and Michigan through Wisconsin. Beginning at the Illinois-Wisconsin state line renumber state trunk highway 42 to a point where it joins the present Wisconsin state trunk highway 32 at Sheboygan; continuing over the present Wisconsin state trunk highway 32 north to the junction with U.S. highway 8 at Laona; continuing over the present Wisconsin state trunk highway 32 north to junction with U.S. highway 45 at Three Lakes; thence north on U.S. highway 45 to Michigan-Wisconsin state line at Land O'Lakes. The department is further directed that in addition to the numeral 32, the highway markers on this highway carry a red arrow, and that historical markers be erected and maintained along the highway in honor of the 32nd Division and its members.
