Sleepy Valley Bridge

Under your assessment categories there is a minor error but significant from the standpoint of Wisconsin history. "Townships" do not own bridges in Wisconsin, whereas "towns" do. Towns exist as political bodies within the state but not "townships." The word "township" is reserved for the surveyor's township. This has to do with the founding dynamics of the local government structure within Wisconsin. Local government was the result of local petitioning at the town level, and towns and counties existed in tension with one another. Counties performed vital functions, mandated by the state, but local affairs belonged to the annual town meeting, and this included most of the political functions, including road and bridge building and elementary education. Modern life has pressured much of these local functions away from towns and toward the county and even the state and federal governments. But towns do retain an important local role in road maintenance and fire prevention and control, and they provide important input into the county zoning regulation process. The Town of Lakeside wherein the Sleepy Valley Bridge rests came into existence as the Town of Amnicon in 1906, in 1910 losing some of its territory and changing its name very shortly to the Town of Lakeside.
