Interstate 41(I-41) is a 175.00-mile-long (281.64 km) north–southInterstate Highwayconnecting the interchange ofI-94andU.S. Route 41(US 41), located about a mile (1.6 km) south of theWisconsinIllinoisborder at the end of the Tri-State Tollway inmetropolitan Chicago,to an interchange withI-43in metropolitanGreen Bay, Wisconsin.The designationtravels concurrentlywith US 41 for its entire length, as well as portions ofI-894,US 45,I-43, and sections of I-94in WisconsinandIllinois.The route was officially added to the Interstate Highway System on April 7, 2015, and connectsMilwaukeeand Green Bay with theFox Cities.

Route description

[edit]

I-41 begins at the I-94/US 41 interchange inRussell, Illinois,located about a mile (1.6 km) south of the Wisconsin–Illinois border at the end of theTri-State Tollway.The highway continues north concurrently with I-94 as part of the North-South Freeway to theMitchell InterchangeinMilwaukee,turns west to run concurrently with I-894 and I-43 as the Airport Freeway to theHale Interchange(forming a briefwrong-way concurrencywith I-43), and turns north to run concurrently as the Zoo Freeway with I-894 andUS 45to theZoo Interchange,with the US 45 concurrency continuing until the I-41/US 41/US 45 split nearRichfield.The Interstate roughly parallels I-43, which runs north–south alongLake Michiganfrom Milwaukee to Green Bay. I-41 runs through theFox Valley(including the cities ofFond du Lac,Oshkosh,andAppleton,along with theFox Cities). At Appleton, I-41 intersectsUS 10andState 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 intersectsWIS 172on 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 175.00 miles (281.64 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.[4]

History

[edit]
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 two places in the United States where three Interstate Highways share the same roadway.

The freeway portion of US 41 andUS 45from Milwaukee through theFox Valleyto 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).[5]

In the initial language of the bill, the route was designated Interstate 41, which correlates with theU.S. Highwayit parallels and also complies with the Interstate naming guidelines through theAmerican 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 ofI-55from its current termination inChicago,with the alternative being designated as a spur of I-43.[6][7]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 theFederal Highway Administration(FHWA) and theIllinois 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, theWisconsin 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).[8]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.[3]Official approval of I-41 then hinged on weight limit exceptions being approved for the route,[9]which initially passed theUnited States House of Representativesas H.R. 4745 and awaited aUnited States Senatevote as S. 2438,[10]but there were later passed in a different bill (H.R. 83) on December 16, 2014.[11][12][13]On April 9, 2015, Wisconsin GovernorScott Walkerannounced that the FHWA had approved I-41 as part of the Interstate Highway System.[14]According to WisDOT, the approval came two days earlier.[2]

WisDOT replaced or modified 3,500 signs before and near September 2015 after coordination with IDOT and the FHWA (signs erected in 2014 and into 2015 before approval of the designation had the I-41 shield obscured until approval).[15][16]Over the next 5–10 years, shoulders are slated to be rebuilt as older parts of the highway are rebuilt.[17][needs update]The redesignation to Interstate status also makes the route subject to theHighway Beautification Act,meaning current advertising billboards along the Milwaukee-to-Green Bay portion of the road can no longer be upgraded or enlarged nor can new signs be added.[18]

Future

[edit]

Beginning in early 2024, WisDOT plans to start several projects to improve I-41 in theAppleton//Fox Citiesmetro area betweenNeenahandDe Pere.The projects will include widening the Interstate from two to three lanes in each direction on a 23-mile-long (37 km) 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 newFox Riverspan south of De Pere with an I-41 interchange. These projects are expected to be completed by 2030.[19][20][21][22]
