Editing U.S. Route 8 (section)

=== 20th century ===
Starting in 1918, the Wisconsin Highway Commission erected highway numbers along state-maintained roadways.<ref name=press-1919-09-20>{{cite news |title = Michigan May Do Well Following Wisconsin's Road Marking System |work = [[The Grand Rapids Press]] |date = September 20, 1919 |page = 10 |oclc = 9975013 }}</ref> The highway across the state from [[St. Croix Falls, Wisconsin|St. Croix Falls]] to [[Armstrong Creek, Wisconsin|Armstrong Creek]] was numbered [[Wisconsin Highway 14|WIS&nbsp;14]] at that time.

The first changes to the routings of the predecessor highways were made by Wisconsin by 1920. A series of curves were added between Turtle Lake and Barron adding "stair steps" to the routing while similar jogs were removed near Cameron, Weyerhauser, Hawkins and Prentice. WIS&nbsp;14 was rerouted between Rhinelander and [[Pelican Lake, Wisconsin|Pelican Lake]] to run via [[Monico, Wisconsin|Monico]], and [[Wisconsin Highway 38|WIS&nbsp;38]] (the future US&nbsp;141) was extended northward from [[Wausaukee, Wisconsin|Wausaukee]] to terminate at the state line near [[Niagara, Wisconsin|Niagara]].<ref name=WI1919>{{cite WisDOT map |year= 1919 |sections= A7–N8}}</ref><ref name=WI1920>{{cite WisDOT map |year= 1920 |sections= 5–6 |pages= 22–27}}</ref> The realignment between Rhinelander and Pelican Lake was shown as reversed by 1922.<ref name=WI1922>{{cite WisDOT map |year= 1922 |sections= 5–6 |pages= 22–27}}</ref> By 1925, the highway in that area was again rerouted to run directly from Rhinelander to Monico, but instead of turning south to Pelican Lake, it was run directly to Crandon. That same year, WIS&nbsp;14 was extended eastward from Armstrong Creek to Pembine and northward to Niagara. The north–south section, previously numbered WIS&nbsp;38, was also redesignated as part of [[Wisconsin Highway 57|WIS&nbsp;57]].<ref name=WI1925>{{cite WisDOT map |year= 1925}}</ref>

US&nbsp;8 was created with the beginnings of the [[United States Numbered Highway System]] on November 26, 1926.<ref name="USH">{{cite web |url = https://www.fhwa.dot.gov/infrastructure/numbers.cfm |title = From Names to Numbers: The Origins of the U.S. Numbered Highway System |work = Highway History |last = Weingroff |first = Richard F. |publisher = [[Federal Highway Administration]] |access-date = April 21, 2009 |date = January 9, 2009 }}</ref> The highway was originally shown on maps running between [[Forest Lake, Minnesota]] and [[Powers, Michigan]].<ref name="USHM">{{cite map |author1 = [[Bureau of Public Roads]] |author2 = [[American Association of State Highway Officials]] |date = November 11, 1926 |title = United States System of Highways Adopted for Uniform Marking by the American Association of State Highway Officials |url = https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |scale = 1:7,000,000 |location = Washington, DC |publisher = [[United States Geological Survey]] |oclc = 32889555 |access-date = November 7, 2013 |via = [[Wikimedia Commons]] |name-list-style = amp }}</ref> At the time, its planned routing was not previously designated as part of the [[Michigan State Trunkline Highway System|State Trunkline Highway System]] in Michigan.

As late as 1959, the [[Michigan State Highway Department]] still had plans to build the section of US&nbsp;8 west of Hermansville to the [[Menominee River]]. The control section atlas published on January 1, 1959, showed this segment of highway on the [[Menominee County, Michigan|Menominee County]] map, complete with a control section number.
