Editing Interstate 40 (section)

===Major projects===
Between May 1980 and March 1982, a major project was conducted on I-40 in Knoxville that widened the route, eliminated several interchanges, added frontage roads, and reconstructed the congestion-prone cloverleaf interchange with I-75, which had earned the nickname "Malfunction Junction", into a three-level stack interchange.<ref>{{cite news |title = Interstate Work Ahead of Schedule; 3 Contracts Signed |url = https://www.newspapers.com/clip/91442063/interstate-work-ahead-of-schedule-3/ |access-date = December 30, 2021 |work = The Knoxville News-Sentinel |date = April 29, 1980 |page = 21 |via = Newspapers.com }}</ref><ref>{{cite news |author = <!--Staff writer(s)/no by-line.--> |title = Junction Bottleneck Officially Broken |url = https://www.newspapers.com/clip/89194354/junction-bottleneck-officially-broken/ |page = C-1 |work = The Knoxville News-Sentinel |date = March 31, 1982 |access-date = November 19, 2021 |via = Newspapers.com }}</ref> This was conducted as part of a larger $250 million (equivalent to ${{formatprice|{{inflation|US-GDP|250000000|1982}}}} in {{inflation-year|US-GDP}}{{inflation-fn|US-GDP}}) road improvement project in the Knoxville area in preparation for the [[1982 World's Fair]].<ref>{{cite book |type = Report |author1 = Knoxville-Knox County Metropolitan Planning Commission |author2 = Barton-Aschman Associates |author3 = Knoxville International Energy Exposition |author4 = K-Trans |date = December 1982 |title = 1982 World's Fair Transportation System Evaluation |url = https://books.google.com/books?id=FYwnAQAAMAAJ |publisher = Office of Planning Assistance, Urban Mass Transportation Administration |page = <!--Multiple--> |id = DOT-I-83-4 |access-date = June 6, 2020 |via = Google Books }}</ref><ref>{{cite book |last = Hunt |first = Keel |author-link =  |date = 2018 |title = Crossing the Aisle: How Bipartisanship Brought Tennessee to the Twenty-First Century and Could Save America |url = https://books.google.com/books?id=h7wpEAAAQBAJ |location = Nashville |publisher = Vanderbilt University Press |pages = 101–102, 117–129, 122 |isbn = 978-0-8265-2241-2 |via = Google Books }}</ref>

Originally, I-40 was constructed through downtown [[Winston-Salem, North Carolina|Winston-Salem]], and it continued to follow that route until a new urban bypass route was built. After the bypass was completed around 1992, I-40 was relocated to the new freeway. The old highway was then redesignated as [[Interstate 40 Business (Winston-Salem, North Carolina)|Interstate&nbsp;40 Business]] (I-40 Bus.), establishing a business route that was actually an expressway for its entire length, a rarity among business routes. Following a reconstruction, the expressway was renamed [[Salem Parkway (North Carolina)|Salem Parkway]] and redesignated as part of [[U.S. Route 421 in North Carolina|US&nbsp;421]].

The "[[Big I]]" interchange in Albuquerque between I-40 and I-25 was reconstructed between 2000 and 2002 in a project that eliminated left-hand entrance ramps and added lanes. This project was given an honorable mention by the [[United States Department of Transportation]] and the FHWA for excellence in urban highway design in 2002.<ref>{{cite web |url = http://www.fhwa.dot.gov/eihd/2002/cat1pic8.htm |title = Excellence in Highway Design - 2002 I-25/I-40 System-to-System Interchange, Albuquerque, New Mexico |publisher = Federal Highway Administration |access-date = November 27, 2011 }}</ref>

The [[Oklahoma City Crosstown Expressway]] was relocated and replaced with a new wider alignment in two phases between May 2002 and October 2012. The old alignment was replaced with [[Oklahoma City Boulevard]], and at-grade thoroughfare.<ref>{{cite web |url = https://www.macokc.com/project/i-40-crosstown/ |title = I-40 Crosstown Realignment |publisher = MacArthur Associated Consultants |location = Oklahoma City |access-date = May 7, 2022 |quote = }}</ref>

In Memphis, the cancellation of the Overton Park stretch of I-240, along with increased traffic volumes and safety hazards, rendered both interchanges with I-240 unable to effectively handle unplanned traffic patterns, thus necessitating their reconstruction. This was accomplished in three phases between January 2001 and December 2016.<ref>{{cite news |last = Adams |first = Tracy |date = June 26, 2003 |title = Honk if you like I-40 relief |url = https://www.newspapers.com/clip/90006239/honk-if-you-like-i-40-relief/ |page = A1 |work = The Commercial Appeal |location = Memphis |access-date = January 30, 2022 |via = Newspapers.com }}</ref><ref>{{cite news |title = TDOT sharpens listening skills |url = https://www.newspapers.com/clip/93776122/tdot-sharpens-listening-skills/ |access-date = January 30, 2022 |work = The Commercial Appeal |date = October 17, 2003 |location = Memphis |page = B4 |via = Newspapers.com }}</ref><ref>{{cite web |url = https://dementconstruction.com/i-40-i-240-interchange-phase-ii/ |title = I-40 / I-240 Interchange – Phase II |author = <!--Not stated--> |date = 2016 |publisher = Dement Construction Company |access-date = February 16, 2020 }}</ref><ref name=commercialappeal06>{{cite news |last = Charlier |first = Tom |url = https://www.newspapers.com/clip/89563429/midtown-i-40-240-project-wraps-up/ |title = Midtown I-40/240 Project Wraps Up; Dangerous curves led to deaths of 8 in 1988 |date = December 10, 2006 |work = The Commercial Appeal |page = B1, [https://www.newspapers.com/clip/89563503/project/ B7] |location = Memphis |access-date = November 26, 2021 |via = Newspapers.com }}</ref>

A $203.7 million two-phase project dubbed "SmartFix 40" resulted in a complete closure of a short stretch of I-40 through Knoxville between May 1, 2008, and June 12, 2009.<ref>{{cite press release |first = Travis |last = Brickey |title = Interstate 40 Reopens In Knoxville 18 days ahead of schedule |url = http://news.tennesseeanytime.org/node/2104 |date = June 12, 2009 |publisher = Tennessee Department of Transportation |url-status = dead |archive-url = https://web.archive.org/web/20090615075026/http://news.tennesseeanytime.org/node/2104 |archive-date = June 15, 2009 |df = mdy-all }}</ref> This was done in order to accelerate the construction timeline, and during this time, through traffic was required to use [[Interstate 640|I-640]].<ref>{{cite news |last = Jacobs |first = Don |date = April 13, 2008 |title = Downtown's 14-month I-40 shutdown will mean new routes, potential surprises |url = https://archive.knoxnews.com/news/local/downtowns-14-month-i-40-shutdown-will-mean-new-routes-potential-surprises-ep-411801200-359923741.html/ |work = The Knoxville News-Sentinel |access-date = January 31, 2021 }}</ref> Both phases of the project won an America's Transportation Award from AASHTO in 2008 and 2010, respectively.<ref>{{cite web |url = https://americastransportationawards.org/2008-2/tn-smartfix40/ |title = TN: SmartFix40 |author = <!--Not stated--> |date = 2008 |publisher = American Association of State Highway and Transportation Officials |access-date = January 31, 2021 }}</ref><ref>{{cite web |url = https://americastransportationawards.org/past-projects/2010-2/tn-smartfix40-phase-2-knoxville-project/ |title = TN: SmartFIX40 Phase 2 Knoxville Project |author = <!--Not stated--> |date = 2010 |publisher = American Association of State Highway and Transportation Officials |access-date = January 31, 2021 }}</ref>
