Interstate 41

{{expand section|date=June 2024}}

I-41 begins at the I-94/US 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 US 45 to the Zoo Interchange, with the US 45 concurrency continuing until the I-41/US 41/US 45 split near 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 Valley (including the cities of Fond du Lac, Oshkosh, and Appleton, along with the Fox Cities). At Appleton, I-41 intersects US 10 and State Trunk Highway 441 (WIS 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 WIS 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 41 to its termination in Green Bay.{{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 41 |access-date = April 7, 2014 }}

The freeway portion of US 41 and US 45 from Milwaukee through the 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).{{cite news |first = Duke |last = Behnke |url = http://www.postcrescent.com/article/99999999/APC0101/709060619/U-S-41-expansion-meets-interstate-standards |title = 'Interstate 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 }}

In the initial language of the bill, the route was designated Interstate 41, which correlates with the 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 41 designated as a northern extension of I-55 from its current termination in Chicago, with the alternative being designated as a spur of I-43.{{cite news |last = Jagannathan |first = Malavika |title = Officials Push to Rename Revamped US 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 }}{{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}} At the spring meeting of the Special Committee on U.S. Route Numbers of AASHTO on May 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).{{cite report |author = Northeast Region |date = May 2012 |title = US 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 }} 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 16, 2012, pending FHWA concurrence.{{AASHTO minutes |year = 2012A |link = yes |access-date = December 23, 2012 }} Official approval of I-41 then hinged on weight limit exceptions being approved for the route,{{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 }} which initially passed the United States House of Representatives as H.R. 4745 and awaited a United States Senate vote as S. 2438,{{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 }} but there were later passed in a different bill (H.R. 83) on December 16, 2014.{{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 }}{{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 }}{{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 }} On April 9, 2015, Wisconsin Governor Scott Walker announced that the FHWA had approved I-41 as part of the Interstate Highway System.{{cite news |url = http://www.greenbaypressgazette.com/story/news/local/2015/04/09/us-named-officially-interstate-highway-system/25529965/ |title = US 41 Named Officially to Interstate Highway System |first = Paul |last = Srubas |date = April 9, 2015 |work = Green Bay Press Gazette }} According to WisDOT, the approval came two days earlier.{{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 }}

Beginning in early 2024, WisDOT plans to start several projects to improve I-41 in the Appleton/Fox Cities metro area between Neenah and 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 span south of De Pere with an I-41 interchange. These projects are expected to be completed by 2030.{{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 }}{{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 }}{{cite web |title = I-41 Project |url = https://i41project.wisconsindot.gov/ |publisher = Wisconsin Department of Transportation |access-date = January 29, 2024 }}{{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}}
