The State of Tennessee has the longest segment of I-40 at {{convert|455|mi|km}}. The Interstate goes through all of the three [[Grand Divisions of Tennessee]] and its three largest cities: [[Memphis, Tennessee|Memphis]], [[Nashville, Tennessee|Nashville]], and [[Knoxville, Tennessee|Knoxville]]. [[Jackson, Tennessee|Jackson]], [[Lebanon, Tennessee|Lebanon]], [[Cookeville, Tennessee|Cookeville]], [[Crossville, Tennessee|Crossville]], and [[Newport, Tennessee|Newport]] are other notable cities through which I-40 passes. Before leaving the state, I-40 enters the [[Great Smoky Mountains]] toward [[North Carolina]].

The section of I-40 which runs between Memphis and Nashville is often referred to as the [[Music Highway (Tennessee)|Music Highway]].<ref>Tennessee public acts 2001 Chapter 100, Senate Bill 916 House Bill 616 Signed into law April 18, 2001, http://www.tennessee.gov/sos/acts/102/pub/pc0100.pdf {{Webarchive|url=https://web.archive.org/web/20090210201103/http://tennessee.gov/sos/acts/102/pub/pc0100.pdf |date=February 10, 2009 }}</ref> During reconstruction, a short section of I-40 through downtown Knoxville near the central [[Spaghetti Junction#Tennessee|Malfunction Junction]] was completely closed to traffic from May&nbsp;1, 2008, and not reopened until June&nbsp;12, 2009, with all traffic redirected via [[I-640]], the northern bypass route. The redesigned section now has additional lanes in each direction, is less congested, and has fewer accidents.<ref>{{cite web |author = Tennessee Department of Transportation |url = http://www.tdot.state.tn.us/smartfix/jwp/ |title = SmartFix: I-40/James White Parkway/Hall of Fame Drive |publisher = Tennessee Department of Transportation |archive-url = https://web.archive.org/web/20101231003123/http://www.tdot.state.tn.us/smartfix/jwp/ |archive-date = December 31, 2010 }}</ref><ref>{{cite web |author = Tennessee Department of Transportation |url = http://www.tdot.state.tn.us/smartfix/jwp/closures.asp |title = SmartFix: I-40/James White Parkway/Hall of Fame Drive |publisher = Tennessee Department of Transportation |archive-url = https://web.archive.org/web/20090429213607/http://www.tdot.state.tn.us/smartfix/jwp/closures.asp |archive-date = April 29, 2009 }}</ref>
