'''Interstate&nbsp;41''' ('''I-41''') is a {{convert|175.00|mi|km|adj=mid|-long}} north–south [[Interstate Highway]] connecting the interchange of [[Interstate 94 in Illinois|I-94]] and [[U.S. Route 41 in Illinois|U.S. Route&nbsp;41]] (US&nbsp;41), located about {{one2a|{{convert|1|mi|km|spell=in}}}} south of the [[Wisconsin]]–[[Illinois]] border at the end of the Tri-State Tollway in [[metropolitan Chicago]], to an interchange with [[Interstate 43|I-43]] in metropolitan [[Green Bay, Wisconsin]]. The designation [[concurrency (road)|travels concurrently]] with US&nbsp;41 for its entire length, as well as portions of [[Interstate 894|I-894]], [[U.S. Route 45 in Wisconsin|US&nbsp;45]], I-43, and sections of I-94 [[Interstate 94 in Wisconsin|in Wisconsin]] and [[Interstate 94 in Illinois|Illinois]]. The route was officially added to the Interstate Highway System on April 7, 2015, and connects [[Milwaukee]] and Green Bay with the [[Fox Cities]].

==Route description==
{{expand section|date=June 2024}}
I-41 begins at the I-94/US&nbsp;41 interchange in [[Russell, Illinois]], located about {{one2a|{{convert|1|mi|km|spell=in}}}} south of the Wisconsin–Illinois border at the end of the [[Tri-State Tollway]]. The highway continues north concurrently with I-94 as part of the North-South Freeway to the [[Mitchell Interchange]] in [[Milwaukee]], turns west to run concurrently with I-894 and I-43 as the Airport Freeway to the [[Hale Interchange]] (forming a brief [[wrong-way concurrency]] with I-43), and turns north to run concurrently as the Zoo Freeway with I-894 and [[U.S. Route 45 in Wisconsin|US&nbsp;45]] to the [[Zoo Interchange]], with the US&nbsp;45 concurrency continuing until the I-41/US&nbsp;41/US&nbsp;45 split near [[Richfield, Washington County, Wisconsin|Richfield]]. The Interstate roughly parallels I-43, which runs north–south along [[Lake Michigan]] from Milwaukee to Green Bay. I-41 runs through the [[Fox River (Green Bay tributary)|Fox Valley]] (including the cities of [[Fond du Lac, Wisconsin|Fond du Lac]], [[Oshkosh, Wisconsin|Oshkosh]], and [[Appleton, Wisconsin|Appleton]], along with the [[Fox Cities]]). At Appleton, I-41 intersects [[U.S. Route 10 in Wisconsin|US&nbsp;10]] and [[Wisconsin Highway 441|State Trunk Highway&nbsp;441]] (WIS&nbsp;441), the latter of which is a freeway that forms a beltway around Appleton by running around the south and east side of the city and back to I-41. Further north, I-41 intersects [[Wisconsin Highway 172|WIS&nbsp;172]] on the south side of Green Bay, before running along the city's west side to its end at the I-43 interchange. The Interstate is {{convert|175.00|mi|km}} long and located almost entirely within the state of Wisconsin and is completely concurrent with a slightly adjusted alignment of US&nbsp;41 to its termination in Green Bay.<ref name=google>{{google maps |url = https://www.google.com/maps/dir/42.4811897,-87.9465899/44.5607489,-88.0541922/@43.529931,-89.3574176,471191m/data=!3m2!1e3!4b1!4m5!4m4!1m0!1m0!3e0!5i1 |title = Overview Map of Interstate&nbsp;41 |access-date = April 7, 2014 }}</ref>

==History==
[[File:Interstate Highways 41, 43, and 894.jpg|thumb|left|upright=0.795|Markers for I-41, I-43, and I-894 on the Airport Freeway, the southern bypass of Milwaukee; this is one of three instances of a [[wrong-way concurrency]] in the United States involving two Interstate highways. It is also one of only three places in the United States where three Interstate Highways share the same roadway.]]
The freeway portion of US&nbsp;41 and [[U.S. Route 45 in Wisconsin|US&nbsp;45]] from Milwaukee through the [[Fox River (Green Bay tributary)|Fox Valley]] to Green Bay was proposed and designated as an Interstate Highway as part of the 2005 highway funding bill ([[Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users]]).<ref name=121806PostCrescent>{{cite news |first = Duke |last = Behnke |url = http://www.postcrescent.com/article/99999999/APC0101/709060619/U-S-41-expansion-meets-interstate-standards |title = 'Interstate&nbsp;41' on Near Horizon |date = September 5, 2007 |work = [[The Post-Crescent]] |location = Appleton, Wisconsin |access-date = August 1, 2013 |url-status = dead |archive-url = https://web.archive.org/web/20140714132836/http://www.postcrescent.com/article/99999999/APC0101/709060619/U-S-41-expansion-meets-interstate-standards |archive-date = July 14, 2014 |df = mdy-all }}</ref>

In the initial language of the bill, the route was designated Interstate&nbsp;41, which correlates with the [[United States Numbered Highway System|U.S. Highway]] it parallels and also complies with the Interstate naming guidelines through the [[American Association of State Highway and Transportation Officials]] (AASHTO). The final bill omitted the I-41 designation. In 2009, Green Bay officials began a campaign to have US&nbsp;41 designated as a northern extension of [[Interstate 55|I-55]] from its current termination in [[Chicago]], with the alternative being designated as a spur of I-43.<ref>{{cite news |last = Jagannathan |first = Malavika |title = Officials Push to Rename Revamped US&nbsp;41 |work = [[Green Bay Press Gazette]] |date = February 8, 2009 |url = https://pqasb.pqarchiver.com/greenbaypressgazette/access/1688989471.html?FMT=ABS |access-date = July 10, 2009 |archive-date = October 21, 2012 |archive-url = https://web.archive.org/web/20121021142757/http://pqasb.pqarchiver.com/greenbaypressgazette/access/1688989471.html?FMT=ABS |url-status = dead }}</ref><ref>{{cite web |author = Village of Howard, Wisconsin |author-link =  Howard, Wisconsin |url = http://www.villageofhoward.com/cm/pdfs/agendasminutes/Village%20Board%202-9-09.pdf |title = New Business, Minutes of the Village Board Meeting |publisher = Village of Howard, Wisconsin |date = February 9, 2009 |access-date = July 10, 2009 }}{{dead link|date=May 2012}}</ref> At the spring meeting of the Special Committee on U.S. Route Numbers of AASHTO on May&nbsp;18, 2012, the I-55 designation was discussed by the committee. Coordination would have been required with the [[Federal Highway Administration]] (FHWA) and the [[Illinois Department of Transportation]] (IDOT) on the I-55 designation.

However, IDOT officials were not interested in signing an extension of I-55 from its Chicago terminus to the state line. Therefore, the [[Wisconsin Department of Transportation]] (WisDOT) decided to seek a different designation not requiring the cooperation of their Illinois counterparts. Four designations were proposed by WisDOT and put up for public review: two new primary designations (I-41 and I-47) and two auxiliary designations (I-594 and I-643).<ref>{{cite report |author = Northeast Region |date = May 2012 |title = US&nbsp;41 Public Information Meeting Report |url = http://www.dot.state.wi.us/projects/neregion/41/docs/ex-pim201205all.pdf |publisher = [[Wisconsin Department of Transportation]] |access-date = December 23, 2012 |url-status = dead |archive-url = https://web.archive.org/web/20140714213808/http://www.dot.state.wi.us/projects/neregion/41/docs/ex-pim201205all.pdf |archive-date = July 14, 2014 |df = mdy-all }}</ref> At the end of October 2012, WisDOT submitted I-41 to AASHTO for consideration at their fall Special Committee meeting, where it was conditionally approved on November&nbsp;16, 2012, pending FHWA concurrence.<ref name=aashto2012-11-16>{{AASHTO minutes |year = 2012A |link = yes |access-date = December 23, 2012 }}</ref> Official approval of I-41 then hinged on weight limit exceptions being approved for the route,<ref name="PostCrescent41ClearsHurdle">{{cite news |last1 = Bollier |first1 = Jeff |title = Interstate Upgrade for 41 Clears Hurdle |work = The Post-Crescent |location = Appleton, Wisconsin |date = December 13, 2014 |page = A4 }}</ref> which initially passed the [[United States House of Representatives]] as H.R. 4745 and awaited a [[United States Senate]] vote as S. 2438,<ref name="Appropriations">{{cite web |title = Appropriations by Fiscal Year: FY2015 |url = https://beta.congress.gov/legislation/appropriations/fy2015 |access-date = September 18, 2014 |publisher = United States Congress }}</ref> but there were later passed in a different bill (H.R. 83) on December&nbsp;16, 2014.<ref name="Post-Crescent">{{cite news |first = Tabitha |last = Cassidy |title = Petri, Ribble Propose Legislation Allowing Existing Trucks to Use the Future I-41 |date = July 5, 2013 |url = http://www.postcrescent.com/article/20130704/APC0101/306200397/Petri-Ribble-propose-legislation-allowing-existing-trucks-use-future-41 |work = The Post-Crescent |location = Appleton, Wisconsin |access-date = August 1, 2013 |url-status = dead |archive-url = https://web.archive.org/web/20141109172911/http://www.postcrescent.com/article/20130704/APC0101/306200397/Petri-Ribble-propose-legislation-allowing-existing-trucks-use-future-41 |archive-date = November 9, 2014 |df = mdy-all }}</ref><ref name="HB83">{{cite web |url = https://www.congress.gov/bill/113th-congress/house-bill/83/text |title = H.R.83: Making Consolidated Appropriations for the Fiscal Year Ending September 30, 2015, and for Other Purposes |date = December 16, 2014 |id = Public Law No: 113–235 |author = ((113th Congress)) |publisher = U.S. Government Printing Office }}</ref><ref>{{cite web |url = http://www.thenorthwestern.com/story/news/local/2014/12/12/highway-interstate-designation-wisconsin/20319573/ |title = Interstate 41 Clears Major Congressional Hurdle |first1 = Jeff |last1 = Bollier |first2 = Nathaniel |last2 = Shuda |name-list-style = amp |date = December 12, 2014 |work = The [[Oshkosh Northwestern]] }}</ref> On April&nbsp;9, 2015, Wisconsin Governor [[Scott Walker (politician)|Scott Walker]] announced that the FHWA had approved I-41 as part of the Interstate Highway System.<ref name="Srubas">{{cite news |url = http://www.greenbaypressgazette.com/story/news/local/2015/04/09/us-named-officially-interstate-highway-system/25529965/ |title = US&nbsp;41 Named Officially to Interstate Highway System |first = Paul |last = Srubas |date = April 9, 2015 |work = Green Bay Press Gazette }}</ref> According to WisDOT, the approval came two days earlier.<ref name="WisDOT2015-04-19">{{cite web |author = ((US 41 Interstate Conversion Team)) |date = April 9, 2015 |title = US 41 Interstate Conversion: Wisconsin State Line–Green Bay, in Kenosha, Racine, Milwaukee, Waukesha, Washington, Dodge, Fond du Lac, Winnebago, Outagamie, and Brown Counties |url = http://www.dot.wi.gov/projects/neregion/41/index.htm |publisher = [[Wisconsin Department of Transportation]] |archive-url = https://web.archive.org/web/20150412025724/http://www.dot.wi.gov/projects/neregion/41/index.htm |archive-date = April 12, 2015 |url-status = dead }}</ref>

==Future==
Beginning in early 2024, WisDOT plans to start several projects to improve I-41 in the [[Appleton, Wisconsin|Appleton]]/[[Fox Cities]] metro area between [[Neenah, Wisconsin|Neenah]] and [[De Pere, Wisconsin|De Pere]]. The projects will include widening the Interstate from two to three lanes in each direction on a {{convert|23|mi|km|adj=mid|-long}} stretch between Appleton and De Pere, upgrading interchanges, reconstructing bridges, and repaving sections of the freeway, along with the new South Bridge Connector project adding a new [[Fox River (Green Bay tributary)|Fox River]] span south of De Pere with an I-41 interchange. These projects are expected to be completed by 2030.<ref>{{cite news |last1 = Voight |first1 = Sophia |title = Construction on I-41 Expansion and New Roundabouts Are Coming to Outagamie County in 2024 |url = https://www.postcrescent.com/story/news/local/2023/12/18/interstate-41-expansion-and-new-roundabouts-coming-to-outagamie-county-in-2024/71911468007/ |access-date = January 29, 2024 |work = The Post-Crescent |location = Appleton, Wisconsin |date = December 18, 2023 |url-access = subscription }}</ref><ref>{{cite web |title = Adjacent Project: I-41 Rehabilitation (Neenah and Appleton) |url = https://i41project.wisconsindot.gov/adjacent-projects |publisher = Wisconsin Department of Transportation |access-date = January 29, 2024 }}</ref><ref>{{cite web |title = I-41 Project |url = https://i41project.wisconsindot.gov/ |publisher = Wisconsin Department of Transportation |access-date = January 29, 2024 }}</ref><ref>{{cite web|url=https://www.browncountywi.gov/departments/highway/general-information/south-bridge-connector/|title=South Bridge Connector Website|publisher=[[Brown County, Wisconsin]]|access-date=17 February 2024}}</ref>
